Rank the following compounds in order of increasing basicity.
- A 4 < 2 < 1 < 3
- B 4 < 3 < 1 < 2
- C 4 < 1 < 3 < 2
- D 2 < 1 < 3 < 4
Answer & Solution
Correct Answer
(B) 4 < 3 < 1 < 2
Step-by-step Solution
Detailed explanation
Compound 1: Aniline (\(C_6H_5NH_2\)) - lone pair on N delocalised into ring via resonance \(\to\) moderate basicity. Compound 2: Benzylamine (\(C_6H_5CH_2NH_2\)) - \(NH_2\) not directly attached to ring, no resonance with ring \(\to\) most basic among these. Compound 3:…
