Chapter 15, Problem 15.95EP

(a)

Interpretation Introduction

Interpretation:

The structural formula of hemiacetal that is formed when acetaldehyde and ethyl alcohol reacts has to be drawn.

Concept Introduction:

Aldehydes contain a carbonyl group that is bonded to a hydrogen atom and a carbon atom.  Ketones are compounds that contain a carbonyl group bonded to two carbon atoms.  Aldehydes and ketones undergo addition reaction across the carbonyl group.

Aldehydes and ketones react with alcohol to form hemiacetal as the product.  This reacts with further molecule of aldehyde or ketone to form acetal.

Hemiacetal is an addition product that is obtained by reaction between aldehyde or ketone with alcohol.  The general reaction of hemiacetal formation can be given as,
