Identify the starting material as a terminal alkyne, specifically a cyclohexylacetylene.
Recognize the reagents used: H3O+ and HgSO4, which indicate an oxymercuration-demercuration reaction.
Understand that the reaction involves the addition of water across the triple bond of the alkyne, following Markovnikov's rule.
The intermediate formed is an enol, which will tautomerize to a more stable ketone.
The major product will be a ketone, where the carbonyl group is formed at the more substituted carbon, resulting in cyclohexyl methyl ketone.
