Textbook Problem

Draw the structural formula of the hemiacetal formed from each of the following pairs of reactants.

  1. a. Acetaldehyde and ethyl alcohol
  2. b. 2-Pentanone and methanol
  3. c. Butanal and ethanol
  4. d. Acetone and isopropyl alcohol

(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,

Explanation

Given reactant are acetaldehyde and ethyl alcohol.  When these two compounds are reacted, hemiacetal is formed.  Ethyl alcohol splits up into two fragments and the alkoxy fragment attaches to the carbonyl carbon atom of acetaldehyde.  The hydrogen fragment attaches to the carbonyl oxygen atom...
