Text Solution

Verified by Experts

The correct Answer is:
D
Covalent bond between two atoms is formed by pairing of electrons present in the valence shell having opposite spins ( orbital overlap concept). Covalent bonds are directional in nature as hybrid orbitals are involved in bond formation which are directed in space in some preferred directions. (valence bond theory).
