Question

Secondary amine is?

• A. An orgnic compound with two $N{H}_2$ groups
• B. A compound with two carbon atoms and an $-N{H}_2$ group
• C. A compound with an $N{H}_2$ group on the carbon atom in number 2 position
• D. A compound in which two of the hydrogens of $N{H}_3$ have been replaced by organic groups.

Answer 1

The correct option is D A compound in which two of the hydrogens of $N{H}_3$ have been replaced by organic groups.

Amines are usually categorized into different types based on their nature. They are usually classified as aliphatic amines (having only Hydrogen and alkyl substituents) and aromatic amines (the nitrogen atom is connected to an aromatic ring).

Secondary amines are those amines that have two organic substituents either alkyl or aryl ones or both. They are bound to the nitrogen together with one hydrogen. A common example includes dimethylamine. Likewise, diphenylamine is an example of an aromatic amine.

Hence option (d) is the correct answer.
