Basic character of an
amine depends upon the ease of formation of the cation by accepting
a proton from the acid The more stable the cation is relative to the
amine, more basic is the amine (a) Alkanamines versus ammonia
Let us consider the reaction of an alkanamine and ammonia with
a proton to compare their basicity Due to the electron releasing nature of alkyl group, it (R) pushes
electrons towards nitrogen and thus makes the unshared electron
pair more available for sharing with the proton of the acid
