In Wilkinson's catalyst, the hybridization of central metal ion and its shape are respectively:

Options

  1. As p 3 d , trigonal bipyramidal
  2. Bd 2 s p 3 , octahedral
  3. Cd s p 2 , square planar
  4. Ds p 3 , tetrahedral

Correct answer

C. d s p 2 , square planar

Step-by-step solution

Wilkinson catalyst [ R h C l P P h 3 3 ] Metal with 4d 8 and 5d 8 Configuration always forms square planar complexes on account of higher CFSE irrespective of weak field or strong field. The magnetic property is diamagnetic.
