Interpretation Introduction

Interpretation:

The complete, detailed mechanism for the reaction of ${\text{LiAlH}}_{\text{4}}$ with $\text{but-2-one}$ is to be drawn.

Concept introduction:

Lithium aluminum hydride $\left({\text{LiAlH}}_{\text{4}}\right)$ is a source of hydride ${\text{(H}}^{\text{-}})$ used to reduce aldehyde and ketone in a protic solvent. Hydride ${\text{(H}}^{\text{-}})$ acts as a nucleophile attached to Al; the $\text{Al -H}$ is broken at the same time $\text{C-H}$ bond is formed.
