Question
Arrange the following in increasing order of their basic strength :
Advertisements
Solution
Reason:-
The -CH3 group will increase the electron density on the benzene ring because of its +I effect, while the NO2 group will decrease the electron density on the benzene ring because of its ‒I effect. Hence, the C6H5-NH2 molecule having -CH3 group will be more basic than C6H5-NH2. Also, it will be more basic than the C6H5-NH2 molecule with the NO2 group.
