Question

Which one of the following molecules has a dipole moment?

a. ) PbCl4
b. ) CS2
c. ) PF5
d. ) F2O
e. ) BF3

Answer 1

A is ionic

B is just like CO2, non polar

C has polar bonds but is octahedral so they all cancel.

D has 2 lone pairs on the oxygen, so it's very polar.

E) Has polar bonds, but they are cancelled out in the trigonal planar structure
