The most suitable reagent for the following conversion is
`H_(3)C-C-=C-CH_(3)to`

Options

A. `Hg^(2+)//H^(+),H_(2)O`
B. Na/liquid `NH_(3)`
C. `H_(2),Pd//C` quinoline
D. `Zn//HCl`

Answer

C

Explanation

(1). `Hg^(2+)//H^(2+),H_(2)Oto` Addition of `H_(2)O` at alkene
(2). Na/liquid `NH_(3)to ` birch reduction (alkyne`to` trans alkene)
(3). `H_(2),Pd//C`, quinolone` to ` reduce alkyne` to `Cis alkene
(4). `Zn//Hclto` reduce alkyne `to` alkyl halide
