The hybridization of the central metal ion and the shape of Wilkinson's catalyst is:
Correct answer: A. dsp2 , square planar
- A. dsp2 , square planar
- B. sp3 , tetrahedral
- C. sp3d, trigonal bipyramidal
- D. d2sp3, octahedral
Explanation
In Wilkinson's catalyst, [RhCI(PPh3)3], the central rhodium (Rh) atom is in a +1 oxidation state with a d electron configuration. With strong field ligands like PPh3 it adopts dsp³ hybridization, which corresponds to a square planar geometry.

About Transition Elements
Transition elements are identified by their partially filled d subshells in atoms or common ions. The topic covers the electronic structure of d-block elements, including the filling order of 4s and 3d orbitals, variable oxidation states and the distinction between transition elements and elements with completely filled d subshells.
