[tex]\alpha[/tex]-terpineol produces four different alkene products (including imonene) when it is dehydrated via E1 mechanism.
On the other hand, 2-methylcyclohexanol produces two different alkenes through E1 mechanism.
Which of these product do you think would be formed in the greatest amount? I personally think 2-methylcyclohexanol will be formed in larger amount. Here's my explanation:2-methylcyclohexanol has more product since alpha-terpineol might have more side reactions during dehydrations. (carbocation+alcohol --> ether / carbocation+alkene --> plymeric alkene)
I am not completely sure. What do you think? Alpha-terpineol or 2-methylcyclohexanol?
