A) 3.66 V
B) 0.80 V
C) -0.80 V
D) -3.66 V
Correct Answer: A
Solution :
Basicity of amines increase with increase in number of -\[\text{C}{{\text{H}}_{\text{3}}}\]groups (or any group which cause +1 effect), due to increase hi electron density on N atom. As a rule, the basicity of t-amine should be more than that of 5-amine, but actually it is found to be lesser than s-amines. This is due to stearic hindrance of bulkier alkyl groups, which decrease the availability of lone pair of electron on the N atom of the amino group. Hence the correct order of basicity is: \[{{\text{(C}{{\text{H}}_{\text{3}}})}_{2}}NH>{{(C{{H}_{3}})}_{3}}N>C{{H}_{3}}N{{H}_{2}}\]You need to login to perform this action.
