Question

If molecule `MX_3` has zero dipole moment, the sigma bonding orbitals used by M (atomic number `lt21`) are
A. sp hybridised
B. `sp^(2)` hybridised
C. `sp^(3)` hybridised
D. None of these

Answer 1

Correct Answer - B
Since, the molecule `(MX_(3))` has zero diple moment, therfore, it must have triangular plnar geometry and accordingly the hybridisation of central metal atom (M) must be `sp^(2)`
