Which of the following is the weakest base?

Options

  1. AEthyl amine
  2. BAmmonia
  3. CDimethyl amine
  4. DMethyl amine

B. Ammonia

Step-by-step solution

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.
