The most suitable reagent for the following conversion, is

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

`Hg^(2+)//H^(+),H_(2)Orarr` Addition of `H_2O` at alkene
(b) Na/liqiud `NH_3 rarr` Birch reduction (Alkyne `rarr` trans alkene)
(c) `H_2,Pd//C` quinoline `rarr` reduce alkyne `rarr` C is alkene
(d) `Zn//HCl rarr` Reduce alkyne `rarr` alkyle halide.
