Question

nitrogen is contained in which class of organic groups

Answer 1

Nitrogen is contained in the class of organic groups known as Amine.

Amine: Organic compounds or the functional group that contains a basic nitrogen atom with a lone pair

Amines are generally organized into categories based on their bonding environments. Amines that have one of their three hydrogen atoms replaced by an alkyl or aromatic substituent are referred to as primary amines. Secondary amines are those that have two substituents and one hydrogen-bonded to nitrogen. Tertiary amines are amines whose hydrogens have been completely replaced by organic substituents. Finally, cyclic amines are those in which the nitrogen has been incorporated into a ring structure, effectively making it either a secondary or tertiary amine. The general structure of an amine contains a nitrogen atom, a lone pair of electrons, and three substituents. However, it is possible to have four organic substituents on the nitrogen, making it an ammonium cation with a charged nitrogen center.

General Formula:

Primary amine : $RNH_2$

Secondary amine : $R_2NH$

Tertiary amine : $R_3N$

where R is an alkyl or aryl group
