Question

Classify each molecule as an aldehyde, ketone, or neither.

Classify each molecule as an aldehyde, ketone, or neither.

Answer 1

Concepts and reason

The structures of several molecules are given and they need to be identified as aldehyde, ketone or neither. The groups responsible for the characteristic chemical properties of a molecule are known as functional groups.

Fundamentals

The functional groups that are asked in the problem are listed below:

• Aldehyde and ketone: Both the groups have a carbonyl group $\left( {{\rm{C = O}}} \right)$ . When the carbonyl group is attached to one alkyl group, then it is known as aldehyde and when both the groups attached are alkyl groups, then it is known as ketone.

Where R, R’, R” are the different alkyl groups.

The aldehyde molecules are as follows:

The ketone molecules are as follows:

The remaining molecules are neither aldehydes nor ketones.
