Multiple Choice

Which of the following functional groups is characterized by a carbonyl group bonded to a nitrogen atom?

Ether

Aldehyde

Alcohol

Amide

Verified step by step guidance

Understand the structure of a carbonyl group, which is a carbon atom double-bonded to an oxygen atom. This is often represented as

C = O

Identify the functional groups listed: Ether, Aldehyde, Alcohol, and Amide. Each has distinct structural features.

Recognize that an Ether consists of an oxygen atom connected to two alkyl or aryl groups, represented as

R - O - R'

, where

R

and

R'

are organic groups.

Understand that an Aldehyde contains a carbonyl group bonded to a hydrogen atom and an alkyl group, represented as

R - C = O - H

Recognize that an Amide is characterized by a carbonyl group bonded to a nitrogen atom, represented as

R - C = O - N H R'

, where

R

and

R'

are organic groups.
