Q. Which of the following compounds is generally used for hydrogenation of alkenes?
A) $Ni(CO)_{4}$
B) $\left\lbrack \left( C_{6}H_{5} \right)_{3}P \right\rbrack_{3}RhCl$
C) $\left( {CH}_{3} \right)_{3}Al$
D) $\left( C_{5}H_{5} \right)_{2}Fe$
Explanation
(b)
${{\lbrack\left( C_{6}H_{5} \right)}_{3}P)}_{3}RhCl\rbrack$ or $\lbrack\left( Ph_{3}P \right)_{3}RhCl\rbrack$ is a Wilkinson’s catalyst, the most widely used of all catalysts for homogeneous hydrogenation.
