Geometry of the complex compounds usually depends upon __________________?
Correct answer: C. hybridization of central metal
- A. type of ligands
- B. types of hybridization in the elements of ligands
- C. hybridization of central metal
- D. All of above
Explanation
In the valence-bond description of coordination compounds, the geometry is predicted from the hybridisation of the central metal orbitals, such as sp3 for tetrahedral and d2sp3 for octahedral complexes. Students may choose all of the above because ligands influence coordination number and bonding, but the stated hybridisation of the central metal is the direct determinant in this model.

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.
