E1 reaction of 3-iodo-4-methylheptane
« on: November 20, 2005, 03:54:32 PM »
Hi,

If you react 3-iodo-4-methylheptane in an E1 fashion, would you get 3-methyl-3-heptene AND 4-methyl-3-heptene?  The book says that we only get the first product (methyl shift), but isn't it also possible to perform a hydride shift and get the second product?  Thanks.

why does it do a methyl shift at all

isn't the resulting cation secondary just as the first one was?

in my eyes it gets more stable only with hydride shift

I think it'll do a hydride shift first in order to make a tertiary cation.
Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex
