Fill in each blank with a general formula for the type of compound formed:

It is defined as the reaction of the addition of the hydroxyl group to an unsaturation bond in the presence of water.

As given alkene reacts with water in the presence of proton so the unsaturated bond is broken, and the stable carbocation formed then hydrogen group from eater attack on carbocation and formed alcohol as shown below:

Hydration Reaction

When alcohol reacts with an alkyl halide, replacement of hydroxyl group occurs with halide ion, and formation of haloalkane occurs as below:

Formation of alkyl halide

On the reaction of an alkene with alkyl halide unsaturated bond breaks, and the halide ion attack on the stable carbocation position, which is formed by breaking the double bond and developing haloalkanes as given:

Formation of alkyl halide
