What happens when water is treated with ethyne and propyne?

Explanation

Alkynes undergo hydration on warming with mercuric sulphate and dilute `H_(2)SO_(4)` at `333K` to form carbonyl compounds.
`underset("Ethene")(CH-=CH)+HOHoverset(Hg^(2+)//H^(+))underset(333K)(to)overset(CH_(2)=C-H)underset(OH)(|)overset("Isomerisation")(to)underset("Acetaldehyde")(CH_(3)CHO)`
`underset("Propyne")(CH_(3)-C-=CH)+HOHoverset(Hg^(2+)//H^(+))underset(333K)(to)overset(CH_(3)-C=CH_(2))underset(OH)(|)overset("Isomerisation")(to)underset("Propan"-2-"ene")overset(CH_(3)-C-CH_(3))underset(O)(||)`
