Current Question (ID: 17595)

Question:

$\text{The most suitable reagent for the following conversion is-}$ $\text{H}_3\text{C} - \text{C} \equiv \text{C} - \text{CH}_3 \rightarrow \text{cis-but-2-ene}$

Options:

1. $\text{Hg}^{2+}/\text{H}^+, \text{H}_2\text{O}$
2. $\text{Na/liquid NH}_3$
3. $\text{H}_2, \text{Pd/C, quinoline}$
4. $\text{Zn/HCl}$

Solution:

$\text{Hint: In this reaction, Lindlar's Catalyst is used.}$ $\text{The Lindlar's catalyst is } \text{H}_2, \text{Pd/C, quinoline.}$ $\text{Lindlar's catalyst permits alkynes to be converted to alkenes without further reduction to an alkane.}$ $\text{Lindlar's Catalyst transforms an alkyne into a cis-alkene because the hydrogenation reaction is occurring on the surface of the metal.}$ $\text{The reaction is as follows:}$ $\text{H}_3\text{C} \equiv \text{CH}_3 \xrightarrow{\text{H}_2, \text{Pd/C quinoline}} \text{H}_3\text{C} = \text{CH}_3$
