Question

The order of basicity of amines in gaseous state is:

$\(1^0 > 2^0 > 3^0 > NH_3$ )

$\(3^0 > 2^0 > NH_3 > 1^?$ )

$\(3^0 > 2^0 > 1^0 > NH_3$ )

$\(NH_3 > 1^0 > 2^0 > 3^0$ )

Answer

$3^0 > 2^0 > 1^0 > NH_3$

Explanation

Solution

The correct order of relative basicity of amines in the gas phase is $\(3^0 > 2^0 > 1^0 > 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 alkyl group, it is not stabilised to such an extent as alkyl ammonium ion.
