Question

Butene-1 may be converted to butane by reaction with

• A. $Zn-HCl$
• B. $Sn-HCl$
• C. $Zn-Hg$
• D. $Pd-H_2$

Answer 1

Answer: (D)

$Pd-H_2$

Answer 2

Butene-1 converts to butane by reaction with $Pd-H_2$. $\underset{\text{Butene}-1}{CH_2 = CH - CH_2CH_3} {->[Pd/H_2][\Delta.\text{pressure}]} \underset{\text{Butane}}{CH_3CH_2CH_2CH_3}$ The other reagents are used in case of polar bonds.
