My question is due to a discrepancy I founndfound in reactivity and organic conversions. In reactivity of organic compounds it has been established that an alkyl group activates the benzene ring, and, hence for example:
-, methylbenzene is more reactive than benzene.
thenThen consider the following situation.
Suppose that there are 2two benzene molecules in a sample, and we convert one of them to toluene (methylbenzene) using Friedel–Crafts alkylation. Then we would see the following change in the mixture:
Now, consider we carry out alkylation once more. Now as TolueneAs toluene is more reactive than benzene, it will react first forming di-methylbenzenedimethylbenzene. By continuing this logic we would get hexa-methylbenzenehexamethylbenzene as the major product regardless of the number of molesamounts we add.
So, how is that we carry out conversions with Friedel–Crafts alkylation regarding toluene as the major product?
