Chapter 12.4, Problem 4LTS

Interpretation Introduction

Interpretation: The product formed by the reaction between aryl ketone and ${\text{LiAlH}}_{\text{4}}$ is to be determined.

Concept Introduction: The hydride ion in ${\text{LiAlH}}_{\text{4}}$ is a good nucleophile. The reaction of ${\text{LiAlH}}_{\text{4}}$ with aldehydes and ketones occurs with the nucleophilic addition of hydride at the carbonyl carbon. The ${\text{Li}}^{+}$ ion works as Lewis acid by coordinating with the carbonyl oxygen.
