`C gt A gt B gt D`

C

`B gt A gt C gt D`

D

`A gt C gt B gt D`

Text Solution

Verified by Experts

The correct Answer is:
D
Compound `(A)` is most basic because the resulting cation is resonance stabilized

Moreover among all the compounds the imino `N` carries negative charge on account of resonance This facilitates protonation

Amides are far less basic than amines on account of resonance as well as inductive effects
Due to the powerful electron-withdrawing effect of the carbony1 group the electron density near the nitrogen atom is quite less

The lone pair on `N` atom is delocalized due to resonance Due to positive inductive effect of two alky1 groups `C` is more basic than `B` .
