Question

An amine on treatment with ` HNO_2` evolved `N_2` The amine on exhaustive methylation with ` CH_3 I` formed a quatermary dalt containing ` 95.07%` iodine . The amine is likely to be:
A. `CH_3NH_2`
B. `(CH_3)_2NH`
C. `C_2H_5NH_2`
D. `(CH_3)_3N`

Answer 1

Correct Answer - C
Evolution of `N_2` with `HNO_2` suggests that `1^2` amine [either (a) or (c ) ].
` 59. 07 gm` if (I) is present in ` 100 gm` of compound ` 127 gm` of (I) ( 1 mol) in present in `(100 xx 127)/( 59. 07) = 215`
