Answer 1

Answer:

What are Amines?

Amines are the organic compounds derived from ammonia (NH3). They are derived by replacing its one or more hydrogen atoms by alkyl or aryl group.

On the basis of the number of hydrogen atoms replaced in NH3 molecule, amines are categorized into three types:

1° or the Primary Amines

In 1° amine, one hydrogen atom of NH3 is replaced by an alkyl or aryl group. For example:

CH3NH2

Methyl Amine

2° or the Secondary Amines

In 2° amine, two hydrogen atoms of NH3 are replaced by alkyl or aryl groups. For example: CH3NHCH3  or Dimethyl Amine

3° or Tertiary Amines

In tertiary amine, all the three hydrogen atoms of NH3 are replaced by alkyl or aryl groups.

Nomenclature of Amines

In the common naming system, we name aliphatic amines by prefixing an alkyl group to a mine, i.e. alkylamine.

Secondary and tertiary amines, having two or more similar groups are named by adding prefix ‘di’ or ‘tri’ before the name of the alkyl group.

Aromatic amines are named as derivatives of the parent member, aniline (C6H5NH2).
