Question

Draw the organic product of the following reaction.

Draw both organic products of the following reaction.

Answer 1

Concept and reason

The concept used is to predict the products of both the reactions.

Fundamentals

Reduction of carbonyl compounds and ester is achieved by reducing agents like ${\rm{LiAl}}{{\rm{H}}_4}$ and ${\rm{NaB}}{{\rm{H}}_4}$ in the presence of acid or water. The nucleophile is ${{\rm{H}}^ - }$ .

The reducing agent that is analogous to ${\rm{LiAl}}{{\rm{H}}_4}$ or ${\rm{NaB}}{{\rm{H}}_4}$ are ${\rm{LiAl}}{{\rm{D}}_4}$ and ${\rm{NaB}}{{\rm{D}}_4}$ . The nucleophile is ${{\rm{D}}^ - }$ .

1.

Reduction of aldehydes with ${\rm{NaB}}{{\rm{D}}_4}$ followed by the hydrolysis results in the formation of corresponding alcohols.

The reaction is as follows:

2.

Reduction of esters with ${\rm{LiAl}}{{\rm{D}}_4}$ followed by the hydrolysis results in the formation of corresponding alcohols.

The reaction is as follows:

Ans: Part 1

The reaction is as follows:

Part 2

The reaction is as follows:
