MCQ
Two electrons of one atom $A$ and two electrons of another atom $B$ are utilized to form a compound $AB.$ This is an example of
  • Polar covalent bond
  • B
    Non-polar covalent bond
  • C
    Polar bond
  • D
    Dative bond

Answer

Correct option: A.
Polar covalent bond
(a) When two atoms shares two electrons it is an example of covalent bond.

This covalent bond may be polar or may be non-polar depends on the electronegativity difference.

In given example formula is $AB.$ So it is polar.
