Chlorination of ethylbenzene in the pres...

Chlorination of ethylbenzene in the presence of light produces 1-chloro-1-phenylethane but not 1-chloro-2phenylethane. Explain.

Text Solution

Verified by Experts

After removal of hydrogen from methylene group of ethylbenzene, `Phoverset(.)CHCH_(3)` is formed. This redical species is resonance stabilised. On the other hand, on removal of hydrogen from methyl group of ethylbenzene, `Phoverset(.)CHCH_(3)` is formed predominantly and it readily reacts with `overset(.)(C)l` to form 1-chloro-1-phenylethane.
