Question

If a molecule MX2 has zero dipole moment, the sigma bonding orbitals used by M (atomic number < 21) are :

Solution

Correct option is

sp hybrid

Dipole moment is vector quantity. 

In trigonal planar geometry (for sp hybridisation), the vector sum of two bond moments is equal and opposite to the dipole moment of third bond.
