Show how would you synthesise the following alcohols from appropriate alkenes?

We know that the addition and elimination reactions are opposite of each other.Hence, for solving the above questions our approach should be to first dehydrate a suitable alcohol to give either a single alkene or a mixture of an alkene, if we obtain a mixture of alkene then we would have to detect which of the alkene will give us the desired alcohol. Wherever required the acid-catalyzed addition of water to alkenes will follow Markovnikov’s rule.

Addition of H₂O to both of these alkenes gives us the desired alcohol.
