Which one of the following compounds will show covalent bonding?
Correct answer: D. H2
- A. CaF2
- B. MgO
- C. KCI
- D. H2
Explanation
Covalent bond is a chemical bond that involves the sharing of electrons,options A, B and C all show ionic bonds, therefore the correct answer will be D.

About Sigma and Pi Bonds
A sigma bond forms by direct end-to-end overlap along the internuclear axis, whereas a pi bond forms by sideways overlap of parallel orbitals. The topic covers single, double and triple bonds, bond composition, restricted rotation and the relation between sigma and pi bonding and orbital hybridisation.
