AMINO
{
In chemistry, amines (, UK also ) are organic compounds that contain carbon-nitrogen bonds. Amines are formed when one or more hydrogen atoms in ammonia are replaced by alkyl or aryl groups. The nitrogen atom in an amine possesses a lone pair of electrons. Amines can also exist as hetero cyclic compounds. Aniline (

) is the simplest aromatic amine, consisting of a benzene ring bonded to an amino (–

{\displaystyle {\ce {NH2}}}
) group.
Amines are classified into three types: primary (1°), secondary (2°), and tertiary (3°) amines. Primary amines (1°) contain one alkyl or aryl substituent and have the general formula
RNH

{\displaystyle {\ce {RNH2}}}
. Secondary amines (2°) have two alkyl or aryl groups attached to the nitrogen atom, with the general formula

NH
{\displaystyle {\ce {R2NH}}}
. Tertiary amines (3°) contain three substituent groups bonded to the nitrogen atom, and are represented by the formula

The general formula for amine is
RNH

{\displaystyle {\ce {RNH2}}}
, where the "R" belongs to an alkyl (or aryl) group.
The functional group −NH2 is called an amino group.
