Thank you! But how many products will it form? Major and minor ? . But how come the minor product in the book didnt put as 1,3 but only on 1?

This is because in this reaction, more double substituted benzenes are formed instead of mono sub

But how many products will it form ? And i still dont get it why the ch3 isnt on the meta carbon as the minor products? But instead its on the first carbon only . Pls help me

This is assuming there is excess alkyl halides and the procress goes on forever. Since the first mono sub is done, with the excess alkyl halide it can undergo more sub easily as alkyl is electron donating, making the ring more susceptible to electrophilic sub

Pls help me. Ure the only one who cn help since no other tutors are here to help me with this sub. Please

Polyalkylation ocvurs when all benzene has been monosub. Only activating group can do this as they are electron donating
