JEE Mains · Chemistry · STD 12 - 9. Amines
The order of basicity of amines in gaseous state is
- A \(1^o > 2^o > 3^o > NH_3\)
- B \(3^o > 2^o > NH_3 > 1^o\)
- C \(3^o > 2^o > 1^o > NH_3\)
- D \(NH_3 > 1^o > 2^o > 3^o\)
Answer & Solution
Correct Answer
(C) \(3^o > 2^o > 1^o > NH_3\)
Step-by-step Solution
Detailed explanation
The correct order of relative basicity of amines in the gas phase is \(3^o > 2^o > 1^o > NH_3\) The alkyl group releases electron and thus, tends to disperse the positive charge of the alkyl ammonium ion and therefore stabilises it. Since, \(NH_4^+\) (from \(NH_3\)) has no such…
