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) $sp$ -hybridised
(c) $sp^{2}$ -hybridised
(d) $sp^{3}$ -hybridised
Show Answer
Answer:
Correct Answer: 44. (c)
Solution:
- For non-polar $M X _3$, it must have triangular planar arrangement, i.e. there should be $sp^{2}$ -hybridisation around $M$.
