Class 11 NEET Chemistry Hydrocarbons Questions

Due to −I effect of F atom, CF3 in benzene ring deactivates the ring and does not favour electrophilic substitution. While −CH3 and −OCH3 are +I group which favor's electrophilic substitution in the benzene ring at 'ortho' and 'para' positions. The +I effect of −OCH3 is more than −CH3, therefore the correct order for electrophilic substitution is
