The functional group is amine.RNH2
With HNO2(NaNO2+HCl) N2 is evolved.This is used to identify primary amine
RNH2 +HNO2-------ROH+ evolution of nitrogen gas
This test is used to differentiate between primary ,secondary ammine.and tertiary ammine.Secondary and tertiary amine do not react to evolve nitrogen gas
