Figure 4
The hydroxide group in alcohols is not a good leaving group in order to perform a nucleophilic substitution reaction on alcohols to produce more compounds. Hydroxide group is made a good leaving group by protonating the hydroxide group in the first step. After then the iodide ion attacks and eliminates protonated hydroxide group to halide product.
