FAQs on Aldol: Reactions due to Alpha Hydrogen Video Lecture - Chemistry Class 12 - NEET

1. What is an aldol reaction?

Ans. An aldol reaction is a type of organic reaction that involves the condensation of an aldehyde or ketone with an enolate or enol to form a β-hydroxy carbonyl compound.

2. What is an alpha hydrogen in the context of aldol reactions?

Ans. In the context of aldol reactions, an alpha hydrogen refers to the hydrogen atom that is attached to the carbon atom adjacent to the carbonyl group in an aldehyde or ketone. It is called the alpha carbon because it is one carbon away from the carbonyl group.

3. Why are alpha hydrogens important in aldol reactions?

Ans. Alpha hydrogens are important in aldol reactions because they can be abstracted by a base to form an enolate, which is a nucleophilic species that can react with another carbonyl compound. The presence of alpha hydrogens allows for the formation of the carbon-carbon bond in the aldol reaction.

4. How many alpha hydrogens are present in a ketone versus an aldehyde?

Ans. Ketones generally have two alpha hydrogens, as they have two alkyl groups attached to the carbonyl carbon. Aldehydes, on the other hand, have one alpha hydrogen, as they have only one alkyl group attached to the carbonyl carbon.

5. Can molecules without alpha hydrogens undergo aldol reactions?

Ans. No, molecules without alpha hydrogens cannot undergo aldol reactions because the formation of an enolate, which is a key intermediate in aldol reactions, requires the abstraction of an alpha hydrogen. Without alpha hydrogens, the necessary nucleophilic species cannot be generated, preventing the aldol reaction from occurring.
