Mark the correct statement [1985]

Detailed Solution: Question 1

Methyl amine is a stronger base than
ammonia due to +I effect. The alkyl groups
which are electron releasing groups increase
the electron density around the nitrogen
thereby increasing the availability of the lone
pair of electrons to proton or lewis acid and
making the amine more basic

Which of the following is more basic thananiline? [2006]

Detailed Solution: Question 24

Benzylamine is more basic than aniline. The reason is that in aniline, the lone pair of nitrogen is conjugated with benzene ring so it is not available readily for others. On the other hand in Benzylamine, nitrogen is not directly attached with ring so lone pairs are
not conjugated with ring.
