Question

The compound F2O has two lone pairs on the central oxygen atom. What's the structure of an F2O molecule? Is this compound polar or non-polar? Question 1 options: A) Bent or angular, polar B) Trigonal planar, polar C) Bent or angular, non-polar D) Trigonal planar, non-polar

Answer 1

Answer:  A) Bent or angular, polar

Explanation:

The central atom oxygen has two lone pairs and two bond pairs in $OF_2$. The number of electron pairs are 4,  that means the hybridization will be $sp^3$ and the electronic geometry of the molecule will be tetrahedral. But as there are two lone pair of atoms around the central oxygen atom, repulsion between lone and bond pair of electrons is more and hence the molecular geometry will be bent shape.

The compound $OF_2$ is polar as the net dipole moment of oxygen - fluoride bonds do not cancel each other out.
