Question

Which one is more basic between methyl amine and methyl sayanide?

Answer 1

hey,

Ethyl amine is more basic than methyl amine due to the higher +I effect of ethyl group.

The lone pair donation tendency depends on the +I effect because repulsive force acts on Nitrogen by +I effect. Hence ethyl amine is more basic by the faster kinetics of lone pair donation. When availability of lone pair is same for 2 amines, we have to go for kinetics of the lone pair donation.
