The hybridization of the central metal ion and 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 (a homogeneous catalyst), (Ph3P)3 RhCl, Rh is dsp2 hybridized giving a square planar shape to the compound.

About Chemical Bonding

Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
