Organic chemistry reactions are easy to understand and based on a particular concept many new pathways are developed on daily basis.Named organic chemistry reactions are such a reactions which are synthetically important and has a vast scope.
In this reaction two carbonyl compounds containing a hydrogen condense in the presence of a base to give ? hydroxy carbonyl compound.
In this reaction carbonyl compounds without hydrogen at a carbon undergo disproportion to give alcohol and salt of carboxylic acid in the presence of a base.
It is the reaction where two ester molecules condense in the presence of base to give condensed ester with alcohol.
In this reduction an acyl chloride is reduced to aldehyde in the presence of Palladium and Barium sulphate as catalytic poison. Here the carbonyl compounds like aldehydes and ketones are directly reduced to alkane in the presence of hydrazine in a suitable base like sodium ethoxide or sodium hydroxide.The mechanism involves formation of hydrazone followed by deprotonation and evolution of nitrogen gives the desired alkane.
Here the carbonyl compounds are reduced to alkanes in the presence of Zinc amalgam in hydrochloric acid. Some Points about Lucas Test:This is the effective test to distinguish the primary, secondary and tertiary alcohols. Organic chemistry reactions are different from inorganic chemistry reactions as the core principle will guide the mechanism of the reaction and the products.For example hydrocarbons on combustion give carbon dioxide and water. Named organic chemistry reactions were discovered pathways by many scientists over the course of time. The strategic application of named reaction is their innovativeness that expand the scope of organic chemistry to new pathways and mechanisms.
Chemical reactions in alcohols occur mainly at the functional group, but some involve hydrogen atoms attached to the OH-bearing carbon atom or to an adjacent carbon atom. As noted in Figure 14.4 "Reactions of Alcohols", an alcohol undergoes dehydration in the presence of a catalyst to form an alkene and water.
Under the proper conditions, it is possible for the dehydration to occur between two alcohol molecules.
Both dehydration and hydration reactions occur continuously in cellular metabolism, with enzymes serving as catalysts and at a temperature of about 37°C.
Although the participating compounds are complex, the reaction is the same: elimination of water from the starting material.
We shall see (in Chapter 14, Section 9 "Aldehydes and Ketones: Structure and Names") that aldehydes are even more easily oxidized than alcohols and yield carboxylic acids.
Unlike aldehydes, ketones are relatively resistant to further oxidation (Chapter 14, Section 9 "Aldehydes and Ketones: Structure and Names"), so no special precautions are required to isolate them as they form.
Note that in oxidation of both primary (RCH2OH) and secondary (R2CHOH) alcohols, two hydrogen atoms are removed from the alcohol molecule, one from the OH group and other from the carbon atom that bears the OH group. Note that the overall type of reaction is the same as that in the conversion of isopropyl alcohol to acetone. Tertiary alcohols (R3COH) are resistant to oxidation because the carbon atom that carries the OH group does not have a hydrogen atom attached but is instead bonded to other carbon atoms.
The first step is to recognize the class of each alcohol as primary, secondary, or tertiary. This alcohol has the OH group on a carbon atom that is attached to only one other carbon atom, so it is a primary alcohol.

This alcohol has the OH group on a carbon atom that is attached to three other carbon atoms, so it is a tertiary alcohol. This alcohol has the OH group on a carbon atom that is attached to two other carbon atoms, so it is a secondary alcohol; oxidation gives a ketone. Alcohols can be dehydrated to form either alkenes (higher temperature, excess acid) or ethers (lower temperature, excess alcohol).
If a starting product does not contain any ? hydrogen atom, the variety of possible products is reduced to two, as this starting product can only act as an electrophilic carbonyl compound, though it cannot act as a nucleophilic enolate.
If benzaldehyde is converted with acetone, for instance, two different products (aside from different stereoisomers) may principally be formed, as acetone may react with benzaldehyde (product "A+B") as well as another acetone molecule (product "A+A"). The product distribution in a crossed aldol reaction, as well as in a "normal" aldol reaction of a unsymmetrical ketone also depends on and can be controlled by the enolates' stabilities. This is the characteristic reaction for carbonyl compounds containing a hydrogen and hence formaldehyde and benzaldehyde will not give aldol condensation.
The purpose of Barium sulphate is reduce to effectiveness of palladium or otherwise the aldehyde thus formed will be directly reduced to alcohol. Here the pthalimide is converted to N-methyl pthalimide which on further base hydrolysis gives the primary amine.
Primary amines on reacting with chloroform and potassium hydroxide form iso-cyanides a foul smell gas which is often used to identify primary amine group in an organic compound.
This method is particularly effective for aryl-alkyl ketones and the substrate should not be acid sensitive.
Primary amines on reactive with carbon disulphide in the presence of mercuric chloride to give iso-thiocyanates.
It shows the intermediates formed during a organic chemistry reaction which can be isolated by adding suitable reagents.Similarly it explains the transition state through which a reactant is converted into product. The organic chemistry field is expanding every day with the invention of new method of synthesis and new compounds. Of the three major kinds of alcohol reactions, which are summarized in Figure 14.4 "Reactions of Alcohols", two—dehydration and oxidation—are considered here. The entire OH group of one molecule and only the hydrogen atom of the OH group of the second molecule are removed. The idea is that if you know the chemistry of a particular functional group, you know the chemistry of hundreds of different compounds. The oxidation reactions we have described involve the formation of a carbon-to-oxygen double bond.
If both carbonyl compounds contain an ? hydrogen atom, both may act as electrophilic carbonyl compound, as well as nucleophilic enol or enolate. However, practically speaking, the reaction basically yields product "A+B", as the electrophilicity and, thus, the reactivity of the aldehyde are considerably higher than that of the ketone. If, for instance, butyl methyl ketone is applied in an aldol reaction, two different enolates are conceivable, as the ketone is asymmetrical.
This reaction indicates the acidic nature of hydrogen at alpha position in the carbonyl compound. In this reaction instead of two ester molecules we can condense ester with another carbonyl compound like acetaldehyde and acetone also.

For example Claisen reaction is named after the scientist Claisen who discovered that esters can be condensed to give condensed products at slightly different conditions. The mechanism is useful in assisting to derive the rate expression and to determine the kinetically controlled and thermodynamically controlled products.
The third reaction type—esterification—is covered in Chapter 15 "Organic Acids and Bases and Some of Their Derivatives", Chapter 15, Section 8 "Preparation of Esters". Because a variety of oxidizing agents can bring about oxidation, we can indicate an oxidizing agent without specifying a particular one by writing an equation with the symbol [O] above the arrow. Thus, the carbon atom bearing the OH group must be able to release one of its attached atoms to form the double bond. Benzaldehyde has no enolizable hydrogens so will be a good acceptor of the enolate anion as it forms. The enolate that contains the higher substituted double bond is relatively more stable than the other one. For example acetaldehyde undergoes aldol condensation to give ? hydroxy butanaldehyde which on dehydration gives crotanaldehyde.This method is excellent synthetic way to prepare unsaturated aldehydes and acids. Some named reactions are named after the reactants, intermediates or products of the reaction. The carbon-to-hydrogen bonding is easily broken under oxidative conditions, but carbon-to-carbon bonds are not.
The enolization in the other direction cannot dehydrate and so that reaction will be reversible.
If tert-butyl methyl ketone is applied in this reaction in place of acetone, only one product is usually obtained, as, due to strong steric interactions, tert-butyl methyl ketone virtually never reacts with any other tert-butyl methyl ketone molecule.
Thus, the enolate with the terminal double bond is less stable than that with the "internal" double bond.
If we take a mixture of acetone and acetaldehyde we will get a condensation product between acetone and acetaldehyde in which the acetone will lose the alpha hydrogen easily to give the product. As a result, the product in an aldol condensation is mainly established by the reaction of the more stable enolate. This mechanism involves formation of carboxylate ion by losing alpha acidic hydrogen and attack of the nucleophile to another carbonyl compound. If the less stable enolate with the terminal double bond ought to be the mainly occuring nucleophile, a considerably bulky base, such as lithium diisopropylamide (LDA), must be applied.
If this were not the case additional products would be possible, due to the problem of regioselectivity.
Due to steric interactions, a sufficiently bulky base tends to abstract the terminal methyl proton.
The first is a kinetic aldol condensation of 2-methylcyclohexanone with propionaldehyde and the second is an aldol between acetone and benzaldehyde.
