Which of the following statements are correct?

A

In gas phase, the basic character of amine is `3^@ gt 2^@ gt 1^@`. Due to the +I effect of `(R^-)`, the availability of LP `bare`'s on N increases.

B

In aqueous medium, the basic character of amine is `Me_2 NH gt Me_3 N gt MeNH_2 gt NH_3`

C

In aqueous medium, the addition of protons increases crowding and thus strains setup, which being the highest in `3^@` amine decreases its basic character.

D

In aqueous medium, the ammonium ions in solution are stabilised not only by alkyl groups but also by H-bond donation to the solvent.

Text Solution

Verified by Experts

The correct Answer is:
A, C, D
The order is: `Me_2 NH gt MeNH_2 gt Me_3 N gt NH_3 (2^@ gt 1^@ gt 3^@ gt NH_3)`
