Q. Which of the following is the weakest base?
A) Ethyl amine
B) Ammonia
C) Dimethyl amine
D) Methyl amine
Explanation
(b)
Alkyl group (an electron releasing ($+ I\ group)\$ increases electron density at N-atom, hence, basic nature is increased. In ammonia, no alkyl group is present, so it is least basic.
