JEE Main Chemistry question
The correct order of basicity of the following compounds is:
(1, acetamidine), (2, ethylamine), (3, dimethylamine), (4, acetamide)
Answer: (B)
Solution
Acetamidine's conjugate acid is strongly resonance-stabilised (positive charge delocalised symmetrically over both nitrogens), making it exceptionally basic — more so than simple alkylamines.
