Arrange the following in increasing order of reactivity towards nitration A. p -xylene B. bromobenzene C. mesitylene D. nitrobenzene E. benzene Choose the correct answer from the options given below
Options
- AC < D < E < A < B
- BD < B < E < A < C
- CD < C < E < A < B
- DC < D < E < B < A
Correct answer
B. D < B < E < A < C
Step-by-step solution
Nitration is an electrophilic aromatic substitution reaction. The + M effect increases the rate of nitration whereas the - M effect decreases the rate of nitration.   - NO 2 ( - M ) ,   - Br ( + M   but   dominant   - I )   and   - CH 3 ( + H ) - NO 2 is strongly deactivating - Br   ,   deactivating - CH 3 ,   activating group D < B < E < A < C
