Chapter 12, Problem 40P

Interpretation Introduction

Interpretation: The structure of two different epoxides that would yield $\text{2-methylpentan-2-ol}\left[{\left({\text{CH}}_{\text{3}}\right)}_{\text{2}}\text{C}\left(\text{OH}\right){\text{CH}}_{\text{2}}{\text{CH}}_{\text{2}}{\text{CH}}_{\text{3}}\right]$ when reduced with ${\text{LiAlH}}_{\text{4}}$ is to be drawn.

Concept introduction: The metal hydride reagents are good reducing agents such as ${\text{LiAlH}}_{\text{4}}$. They can be used to reduce carbonyl compounds, conjugated double or triple bonds and $\text{C}-\text{X}$ bond in alkyl halides and epoxides. The epoxide rings open up to form alcohol.
