The product of this hydration reaction would be 1-methylcyclopentanol.
Work Step by Step
The picture attached to this answer shows the mechanism that takes place to form 1-methylcyclopentanol. Steps: 1) Protonation of the double bond forms a carbocation at the most substituted carbon. 2) Nucleophilic attack by water gives a protonated alcohol. 3) Deprotonation with another water molecule gives the alcohol.
