When the central atom of coordination compound is sp3d2 hybridization the expected geometry will be___________________?
Correct answer: D. octahedral
- A. tetrahedral
- B. square planar
- C. trigonal bipyramidal
- D. octahedral
Explanation
sp3d2 hybridisation provides six equivalent hybrid orbitals, so six ligand positions are arranged around the central atom in an octahedral geometry. The likely mistake is choosing trigonal bipyramidal, which has five positions and is associated with sp3d hybridisation.

About Electronic Structure of d-Block Elements
The electronic structure of d-block elements covers the filling of the (n-1)d and ns orbitals, general electronic configurations, and the exceptions shown by chromium and copper. It explains how partially filled d orbitals produce variable oxidation states, coloured ions, magnetic behaviour and complex formation, while distinguishing transition elements from elements with completely filled d subshells.
