Excess of `CH_(3)COOH` is reacted with `CH-=CH` in presence of `Hg^(2+)`, the product is -

Options

A. `overset(CH_3)overset(|)CH(CH_3COO)_2`
B. `{:(CH(CH_3COO)_2),(|),(CH(CH_3COO)_2):}`
C. `overset(CH_3)overset(|)CH_(2)(CH_3COO)`
D. None of these

Answer

A

Explanation

Reaction of acetic acid with acetylene is catalysed by `Hg^(2+)` salts.
`underset("Acetylene")(HC=CH) overset(CH_3COOH)underset(Hg(OOC CH_3)_2)rarrCH_(2)=underset("vinyl acetate")(CHOOC CH_3)overset(CH_3COOH)underset(Hg(OOC CH_3)_2)rarrCH_3-underset("ethylidene diacetate")(CH(OO C CH_3)_2)`
