(a)

Interpretation Introduction

Interpretation:

It should be determined that the product obtained from the reaction of Ethyl butanoate with ${\text{LiAlH}}_{\text{4}}$ followed by treatment with dilute acid.

Concept introduction:

${\text{LiAlH}}_{\text{4}}$ is a powerful reducing agent which reacts violently with water, alcohol and reduces carbonyl, carboxylic acid and ester.

Reduction of carbonyl, carboxylic acid and ester using ${\text{LiAlH}}_{\text{4}}$ yields corresponding alcohols.

Reduction of an ester (Methyl-2-pentenoate) by using ${\text{LiAlH}}_{\text{4}}$ in presence of dilute acid is shown below,

Interpretation Introduction

Interpretation:

It should be determined that the product obtained from the reaction of Pentatonic acid

with ${\text{LiAlH}}_{\text{4}}$ followed by treatment with dilute acid.

Concept introduction:

${\text{LiAlH}}_{\text{4}}$ is a powerful reducing agent which reacts violently with water, alcohol and reduces carbonyl, carboxylic acid and ester.

Reduction of carbonyl, carboxylic acid and ester using ${\text{LiAlH}}_{\text{4}}$ yields corresponding alcohols.

Reduction of a carboxylic acid (oleic acid) by using ${\text{LiAlH}}_{\text{4}}$ in presence of dilute acid is shown below,
