Answer & Solution
Correct Answer
(B) (C), (D), (B), (A)
Step-by-step Solution
Detailed explanation
Compare basicity: Aliphatic amines (\(C, D\)) > Aromatic amines (\(A, B\)). For aliphatic amines: \((\text{C}_2\text{H}_5\text{)}_2\text{NH}\) (C) > \(\text{CH}_3\text{NH}_2\) (D) due to greater +I effect and optimal solvation. For aromatic amines:…
