Question

Which one of the following molecules is non-polar?

CH₃Br

IF₃

PF₅

SOCl₂

CH₃Cl

Answer 1

1)

CH3Br is tetrahedral.

Due to different bonds, it is polar.

2)

In IF3, I has lone pair on it.

So, this is polar.

3)

PF5 is non polar.

It is trigonal bipyramidal and all the bonds are same.

Due to symmetry, its non polar

4)

SOCl2, O ha lone pair.

So, this is polar.

5)

CH3Cl is tetrahedral.

Due to different bonds, it is polar.

Answer: PF5
