N is single bonded to R, and single bonded twice to H.
Explanation:
The functional group present in an amine will not be complete without mentioning the nitrogen group present in the compound.
Amines are organic compounds that show appreciable basicity. They are regarded as the derivatives of ammonia where one or two or the three hydrogen atoms has/have been replaced been replaced by alkyl or aryl groups.
Amines are classified as primary, secondary or tertiary based on the number of substituted hydrogen atoms they carry.
The nitrogen bonded to the R - aryl group and bonded to hydrogen is a good description of the functional group.
