In the reaction
`Ph-C-=C-CH_(3)underset(HgSO_(4))overset(H_(3)O^(+))toA,` A is

In the reaction Ph-C-=C-CH_(3)overset(H_(3)O^(+))underset(HgSO_(4))rarrA, A is

Ph-C-=C-CH_3overset(Hg^(2+))underset(H_3O^+)toA .Here A is -

Ph-C -= C - CH_3 overset(HgSO_4)underset(H_2SO_4) to A ,

Ph-C -= C - CH_3 overset(HgSO_4)underset(H_2SO_4) to A ,
