Wilkinson's catalyst has the formula

Options

A. `Co(acac)_(3)`
B. `p[Co(N_(2))(H)(PPh_(3))_(3)]`
C. `[Ir(CO)(CI)(PPh_(3))_(2)]`
D. `[Rh(CI)(PPh_(3))_(3)]`

Answer

D

Explanation

Wilkinson's catalyst `[Rh(C1)(PPh_(3))_(3)]` is red-videt in colour, and is made by refluxing `RhC1_(3)` . `3H_(2)O` with triphenylhosphine. It has a square planar structure. It is very effective for selective hydrogenation of organic molecules at room temperature and presure. Alkene groups at the end of a chain (alk-1-enes) are hyrogenated but double bonds elsewhere in the chain are not affected. It is of importance in the pharmaceutical industry.
