Answer» Correct Answer - D
`CH-=CH+H-O-overset(O)overset(||)(C)-CH_(3)overset(Hg^(2+))toCH_(2)=underset("Vinylacetate")(CH-O-overset(O)overset(||)(C)-CH_(3))`
`CH_(2)=CH-O-overset(O)overset(||)(C)-CH_(3)underset(Hg^(2+))overset(CH_(3)-overset(O)overset(||)(C)-OH)tounderset("Ethylidene diacetate")(CH_(3)CH(OOC CH_(3))_(2))`
