Show the mechanism that illustrates the following reaction.
1-methyl-1-methanol-cyclopentane + acid -> 1-methyl-cyclohexene
So, there is an elimination reaction, *AND* the carbon ring grows from a five carbon ring to a six carbon ring.
(I hope my IUPAC name for 1-methyl-1-methanol-cyclopentane is correct. One methyl group and one methanol group are attached to the same carbon on a cyclopentane structure).
I don't know the mechanism for your reaction but I'm posting this to let you know that we simply can't draw mechanisms on these boards. Sorry about that.
