230437 Butene-1 may be converted to butane by reaction with:

1

Zn - HCl

2

Sn - HCl

3

Zn - Hg

4

P d / H 2

Explanation:

: Alkene can be converted to alkanes by addition of hydrogen $(H_{2})$ . In a hydrogenation reaction, two hydrogen atom are added across the double boond of an alkene, resulting in a saturated alkane. The reaction occurs in the presence of a catalyst like nickel, platinum or palladium.
