If the assertion is true but the reason is false.
If both the assertion and reason are false.
The basicity of aniline is weaker in comparison to that of methylamine due to:
hyper conjugative effect of Me-group in MeNH2
resonance effect of the phenyl group in aniline
the lower molecular weight of methylamine as compared to that of aniline
resonance effect of -NH2 group in MeNH2
An amine C3H9N reacts with benzene sulphonyl chloride to form a white precipitate which is insoluble in aq. NaOH. The amine is
The reaction of aniline with chloroform under alkaline conditions leads to the formation of
phenylcyanide
phenylisonitrile
phenylcyanate
phenylisocyanate
In the reaction,
A is
HgSO4 /H2SO4
Cu2Cl2

When diazonium salt is treated with H3PO2 followed by hydrolysis, it diazonium group is replaced by H resulting to the formation of hydrocarbon. Thus, A must be H3PO2 / H2O.
