Hey guys,

I was just wondering why the propyl group gets rearranged in the reaction. I don't remember any mention of this anywhere in the Kaplan book.

The reacion is AlCl3
Benzene + CH3CH2CH2CL -----> Benzene CH(CH3)CH3


Thank you

i think it's just soemthing to know that if you're doing alkylation with more than 3 carbon chain, rearrangement occurs to give you most stable chain.

This is too complicated, it happens, but we never know if it does happen. And some of it will not rearrange. unfair question, but you should understand why it happens. just remember the pos charge on the primary carbon is not favorable so rearrangement happens to move it to the carbon next to it.
