Chapter 20, Problem 87IP

Interpretation Introduction

Interpretation: The major product of the given reaction has to be found.

Concept Introduction:

• ${\text{LiAlH}}_{\text{4}}$ - Lithium aluminium hydride is a reducing agent.
• It reduces aldehydes, ketones and carboxylic acids into alcohols.
• It also reduces cyclic esters into alcohols. Such a reduction takes place in the following two steps:
  • First the cyclic ester will be converted into an aldehyde by the first equivalent of ${\text{LiAlH}}_{\text{4}}$.
  • Then the aldehyde will be converted into an alcohol by the second equivalent of ${\text{LiAlH}}_{\text{4}}$.
