Chemical Bonding - Result Question 69
####44. If a molecule $M X _3$ has zero dipole moment, the sigma bonding orbitals used by $M$ (atomic number <21) are
(a) pure $p$
(b) $s p$-hybridised
(c) $s p^{2}$-hybridised
(d) $s p^{3}$-hybridised
Objective Questions II
(One or more than one correct option)

Solution:
- For non-polar $M X _3$, it must have triangular planar arrangement, i.e. there should be $s p^{2}$-hybridisation around $M$.
