Introduction

Amines of Class 12

Amines are the alkyl (or) aryl derivatives of NH3. The general formula of amine is R 3 N, where R is an alkyl (or) aryl group or hydrogen.

Amines

In amines one or more Hydrogen atoms of ammonia are replaced by Alkyl or aryl groups. Here nitrogen atom of amines is like that of NH 3 , it is sp 3 hybridised. The three Alkyl groups (or hydrogen atoms) occupy corners of a tetrahedron, one of sp 3 orbital occupying the unshared electron pair directed towards the other corner. We say shape of amine as “Trigonal Pyramidal”.
