Structure of both products are given below.Explanation:This reaction is an example of oxymercuration reaction of double bond.Here ion makes coordination with double bond in first step resulting formation of a complex having transient carbocationic character. In the second step, a water molecule attacks the above complex at more substituted position and forms an enol (initial product) subsequently.Enol is being tautomerized and converted to a ketone (final product)Full mechanism has been shown below....
