Chapter 17, Problem 17.64P

Interpretation Introduction

(a)

Interpretation:

Highlight the aldehyde or ketone group in given compounds.

Concept Introduction:

Both aldehydes and ketones contain $(>\text{C}=\text{O})$ i.e., carbonyl group. The general formula of aldehyde group is as follows:

$\text{H}-\text{CO}-\text{R}$

Here, r is alkyl group.

The general formula of ketone group is as follows:

${\text{R}}^{\text{'}}/\text{R}-\text{CO}-\text{R}$

Here, r and ${\text{R}}^{\text{'}}$ are alkyl groups.

Answer to Problem 17.64P

Explanation of Solution

Both aldehydes and ketones contain $(\text{C}=\text{O})$ i.e., carbonyl group. Except formaldehyde, in all aldehydes the carbonyl group is bonded to one hydrogen and one carbon atom. The aldehyde group may be written as $\text{-CHO}$. In a ketone, a carbonyl group is bonded to two carbon atoms. Therefore, given compound contains one aldehyde and one ketone group.
