WebAnd that is a tertiary carbocation. And we know tertiary carbocations are more stable than secondary carbocations. Next, since this is an E1 mechanism, we know that a weak base comes a long and takes a proton. So in this case, we could take a proton from a few different places. We could take a proton from this carbon.
