The relative rates of mononitration of R – C6H5, where R = CH3, – NO2, – OH, – Cl are
A
CH3> OH > NO2>Cl
B
OH >Cl> CH3> NO2
C
OH > CH3> NO2>Cl
D
OH > CH3>Cl> NO2
Answer
OH > CH3>Cl> NO2
Explanation
Solution
In presence of +M effect rate of mononitration increase and in presence of –M effect rate will decreases
