Show how would you synthesisse the following alcohols form approprite alkenes.
i. ii.
iii. iv.

Explanation

The alkenes ofr synthesising the alcohols can be obtained by first dehydrating the alcohol to give either a single alkene or a mixture of alkene. If a mixture of alkenes is possible then find out which alkene gives the desired alcohol. The acid catalysed addition of `H_(2)O` to alkenes occurs in accordance with the Markownikoff's rule.
