Correct order of basicity of NH_2 (A), p-CH_3OC_6H_4NH_2 (B), o-CH_3OC_6H_4NH_2 (C) and (D) a further methoxyaniline isomer is

JEE Main Chemistry question

Correct order of basicity of (A), - (B), - (C) and (D) a further methoxyaniline isomer is

(A)A > B > C > D
(B)D > C > A > B
(C)B > D > C > A
(D)D > A > B > CCorrect

Answer: (D)

Solution

Electron-donating groups (such as ) increase the basicity of an aromatic amine by reinforcing electron density at nitrogen, while electron-withdrawing groups decrease it; unsubstituted aniline sits in between the more activating and more deactivating substituted anilines. Ranking the
