Chapter 18, Problem 18.1YT

Interpretation Introduction

Interpretation:

The hemiacetal of $\text{butan-2-one}$ in which the $\text{OR}$ group is a butoxy(${\text{OCH}}_{\text{2}}{\text{CH}}_{\text{2}}{\text{CH}}_{\text{2}}{\text{CH}}_{\text{3}}$) group is to be drawn.

Concept introduction:

The hemiacetal is a class of an organic compound in which a carbon atomis bonded to both an $\text{OH}$ group and an $\text{OR}$ group. When the carbonyl compounds (an aldehyde or ketone) are treated with alcohol in the presence of an acid or base, the corresponding hemiacetal is formed.
