Arrange the following in the order of decreasing basicity
$RN = CHR^{1} RC \equiv N RNH_{2} I II III$

Question

Arrange the following in the order of decreasing basicity RN= CHR^1 RC ≡N RNH_2I II III

Accepted Answer

Correct answer: B. (b) In RNH_2 , N atom is sp^3 hybridised. In RN= CHR^ ', N atom is sp^2 hybridised whereas in RC ≡N ,N atom is sp hybridised. The sp hybridised N atom is most electronegative due to maximum s character. More electronegative element has less tendency to donate electrons and therefore is least basic. The order of basicity of aliphatic amines should be primary > secondary > tertiary. Thus, the order of basicity will be: RNH_2> RN= CHR^ '> RC ≡N III I II

$Arrange the following in the order of decreasing basicity RN = CHR^{1} RC \equiv N RNH_{2} I II III$
