Question

Classify each structure according to its functional class. A. Select answer ether amide ketone amine alcoholB. Select answer C. Select answer D. Select answer

Answer 1

Concepts and reason

The structures of several molecules are given and the functional groups need to be identified. The groups responsible for the characteristic chemical properties of a molecule are known as functional groups.

Fundamentals

The several functional groups that a molecule can possess are listed below:

• Alcohol: The alcohol group is represented as -OH.

• Amine: It is represented as $- {\rm{N}}{{\rm{H}}_2}$ .

• 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.

• Amide: It is represented as $- {\rm{CON}}{{\rm{H}}_2}$ . It is shown below:

• Ether: When an oxygen atom is attached to two alkyl groups, then it is known as ether group. It is represented as R-O-R’, where R and R’ are different alkyl groups.

A.

The functional group present in the molecule is ketone.

B.

The functional group present in the molecule is ether.

C.
