If a molecule `MX_(3)` has zero dipole moment , the sigma bonding orbitals used by M are

A

pura`P`

B

sp-hybridised

C

`sp^(2)`-hybridised

D

`sp^(3)` hybridised

Text Solution

Verified by Experts

The correct Answer is:
C
Dipole momnet is a vector quantity
In trigonal planar geometry (for `sp^(2)` hybridisation) the vector sum of two bond moments is equal and oposite to the dipole moment of third bond .
