Assertion (A) : Toluene on Friedal Crafts methylation gives o-and p-xylene. Reason (R) : CH_(3) group bonded to benzene ring increases electron density at o-and p-position.

Assertion (A) : Toluene on Friedal Crafts methylation gives o-and p-xy

1.	Assertion (A) : Toluene on Friedal Crafts methylation gives o-and p-xylene. Reason (R) : CH_(3) group bonded to benzene ring increases electron density at o-and p-position.
Answer» Both A and R are correct and R is the correct explanation of A. Both A and R are correct and R is not the correct explanation of A. Both A and R are not correct. A is not correct but R is correct. Solution :Toluene has `-CH_(3)` group ATTACHED to benzene RING. `CH_(30` group is electron withdrawing group which activates benzene ring due to hyper-conjugation effect, and increases electron density on ortho and parapositions for the attack of electrophiles.
