What happens when hydroxymethyltrimethylcyclopentanol reacts with concentrated HCl?
Accepted Answer
When hydroxymethyltrimethylcyclopentanol reacts with concentrated HCl, it undergoes an acid-catalyzed dehydration reaction to form 1,2-dimethyl-1-cyclopentene and water. The reaction proceeds via a carbocation intermediate. Here is the mechanism for the reaction:

The first step is the protonation of the hydroxyl group by the hydrogen ion from the HCl, which forms a water molecule and a carbocation intermediate. The carbocation intermediate then rearranges to form a more stable carbocation, which then loses a proton to form the alkene product.
