The species which donate two electron pairs in a coordination compound is called__________________?
Correct answer: D. bi-dentate ligand
- A. ligand
- B. mono-dentate ligand
- C. poly-dentate ligand
- D. bi-dentate ligand
Explanation
A ligand that donates two electron pairs through two donor atoms is called a bidentate ligand, such as oxalate or ethylenediamine. The likely alternative is polydentate ligand, but that is the broader term for ligands donating three or more electron pairs, whereas two donor pairs specifically means bidentate.

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.
