Question

The coordination complex chloridotris (triphenylphosphine) rhodium (l) is used in the hydrogenation of alkenes. It is also known as ________ catalyst.

• A. Grubb
• B. Pearlman
• C. Wilkinson
• D. Ziegler-Natta

Answer 1

The correct option is C Wilkinson

$(P{h}_{3}P{)}_{3}RhCl$ is Wilkinson catalyst
$H_{2}C=C{H}_2\stackrel{(P{h}_{3}P{)}_{3}RhCl}{\to }{H}_{3}C-C{H}_3$
Co-ordination compounds may be used as homogeneous or heterogeneous catalysts for many reactions. Wilkinson catalyst is used as a homogenous catalyst in hydrogenation of alkenes, whereas Ziegler-Natta catalyst is used as a heterogeneous catalyst for the polymerisation of olefins.
