Question

The hybridisation, oxidation number of central metal ion and shape of Wilkinson's catalyst are

• A. $d s p^{2},+1,$ square planar
• B. $s p^{3},+4,$ tetrahedral
• C. $s p^{3} d,+2,$ trigonal bipyramidal
• D. $d^{2} s p^{3},+6,$ octahedral.

Answer 1

Answer: (A)

In Wilkinson's catalyst-(a homogeneous catalyst), $\left( Ph _{3} P \right)_{3} Rh Cl , Rh$ is $d s p^{2}$ hybridised giving a square planar shape to the compound and is in $+1$ oxidation state.
