You mean alkyne Huh?Well. add HgSO4/H2SO4. Also be more specific about the alkene and ketone you want because the question is quite ambiguous.

If you are reffering to ALKYNE then the method quoted by Sandeep is correct. Alkynes on hydration with dilute sulphuric acid in presence of mercuric sylphate gives ketone.
