`H_(3)C=C=Choverset(Hg^(+2)//H_(2)SO_(4))rarrXoverst(KMnO_(4))rarrY:`

In the following sequence of reaction, the end product is : HC-=CHoverset(Hg^(2+)//H_(2)SO_(4))rarr(A) overset(CH_(3)MgX)underset([H_(2)O])rarr(B)overset([O])rarr(C)

H_3C -C -= overset(Hg^(+2)// H_2SO_4) to X overset(KMnSO_4)to Y :

Predict the correct intermediate and product in the following reaction: H_(3)C-C-=Choverset(H_(2)O,H_(2)SO_(4))underset(HgSO_(4))to"Intermediate" to "Product"

Write the structure of products of the H_(3)C-C-=C-H overset(Hg^(2+), H_(2)SO_(4))to reaction.
