Which of the following is a polar molecule?
- ASiF4
- BXeF4
- CBF3
- DSF4
View written solutionFree
Correct answer: D
The given molecules SiF4, XeF4, and BF3 are symmetric molecules that is why due to cancellation of bond dipoles they are non-polar even though they contain polar
bonds.
But in SiF4 there are four Si—F bonds and one lone
pair due to which its structure is unsymmetrical.
Hence, it is a polar molecule.
