Draw the structures of the two carbocation intermediates that might form during the reaction of the alkene (below) with HCl. If the two carbocations differ in stability, draw a reaction arrow from the less stable to the more stable. Make sure that the arrow points from the less stable to the more stable carbocation intermediate.
