The increasing order of basicity of the following compounds is :
1 (B) \( < \) (A) \( < \) (C) \( < \) (D)
2 (B) \( < \) (A) \( < \) (D) \( < \) (C)
3 (D) \( < \) (B) \( < \) (A) \( < \) (C)
4 (A) \( < \) (B) \( < \) (C) \( < \) (D)
Explanation:
Order of base nature depends on electron donation tendency. (1) In compound N is \(\mathrm{sp}^{2}\) hybridized so least basic among all given compound. (2) compound is very strong nitrogenous organic base as lone pair of one nitrogen delocalize in resonance and make another nitrogen negatively charged and conjugate acid have two equivalent resonating structure. Thus it is most basic in given compounds (3) (Secondary amine) is more basic than (Primary amine).

The correct basic strength order is
1 I \(>\) II \(>\) IV \(>\) III
2 IV \(>\) III \(>\) II \(>\) I
3 III \(>\) II \(>\) IV \(>\) I
4 III \(>\) IV \(>\) II \(>\) I
Explanation:
In (I), -I effect on both sides of NH In (II), -I effect on one side (III) is aliphatic primary amine (IV) is aromatic primary amine The basicity order will be III \(>\) IV \(>\) II \(>\) I.

Which electron displacement effect explains the following correct order of acidity of the carboxylic acids ? \(\mathrm{Cl}_{3} \mathrm{CCOOH}>\mathrm{Cl}_{2} \mathrm{CHCOOH}>\mathrm{ClCH}_{2} \mathrm{COOH}\)
1 Inductive effect
2 Mesomeric effect
3 Electromeric effect
4 Hyperconjugation
Explanation:
"Cl" stabilises the carboxylate ion by \(-\mathrm{I}\) effect. Hence \(\mathrm{Cl}_{3} \mathrm{CCOOH}\) is more ionised as its anion is more stabilised by more -I effect.
