Develop a synthesis pathway to to accomplish this task. Please help. I got 2 Pentanone from 2-pentyne but I dont know how to get 3-Pentanone. Thanks

3-pentanone can be synthesized from 2-pentyne in an acid catalyzed hydration reaction (the intermediate step with the double bond is shown between the 2-pentyne and 3-pentanone):
CH3CH2C -(triple bond) - CCH ---> CH3CH2C(OH) -(double bond) - CHCH3 ---> CH3CH2C -(double bond with the oxygen) - O CH2CH3
Please add H2O (hydrolysis) above the first arrow and H2SO4 (acid) and HgSO4 (catalyst) below the arrow to reflect the acid catalyzed hydrolysis reaction.
(FYI....this reaction also produces 2-pentanone, i.e., the reaction produces 2 ketones.)
Hope this helps...good luck!
