Current Question (ID: 21332)

Question:

$\text{Butene may be converted to butane by a reaction with:}$

Options:

1. $\text{Zn - HCl}$
2. $\text{Sn-HCl}$
3. $\text{Zn-Hg}$
4. $\text{Pd/H}_2$

Solution:

$\text{Butene conversion in butane is a reduction reaction.}$ $\text{In this reaction, addition of hydrogen atoms takes place.}$ $\text{For this reaction reducing agent is used.}$ $\text{Hence, the best reducing agent is H}_2 \text{ in the presence of Pd.}$ $\text{The reaction is as follows:}$ $\text{H}_2\text{C} = \text{C} - \text{C} - \text{CH}_3 \xrightarrow{\text{H}_2, \text{Pd}} \text{H}_3\text{C} - \text{C} - \text{C} - \text{CH}_3$ $\text{other reagents are successful with polar double bonds}$
