Question

Consider the Hofmann ammonolysis reaction :
`R-X +ddotNH_(3)rarr underset(1^(@) amine)(HX + RNH_(2)) overset(R-X)underset(373K)rarr`

If `R = C_2H_5`, the correct of basic character of the above amines in aqueous medium is :
A. `2^@ gt 3^@ gt 1^@ gt NH_3`
B. `2^@ gt 1^@ gt 3^@ gt NH_3`
C. `3^@ gt 2^@ gt 1^@ gt NH_3`
D. `NH_3 gt 1^@ gt 2^@ gt 3^@`

Answer 1

Correct Answer - A
(a) In gaseous or nonpolar solvent, the basic order is `3^@ gt 2^@ gt 1^@ gt NH_3`.
