Question

For each molecule below, specify the polarity of the bonds and the overall polarity of the molecule.? Are the bonds for each one polar or non polar? Are the molecules for each one polar or non polar? BeCl2 O3

Answer 1

The bonds in each case are polar; however, BeCl₂ is non polar due to its linear structure. The molecule has a net dipole moment of 0.
The O₃ molecule is polar because both ends attract the electrons of the central Oxygen, leaving it with an overall positive charge and the ends with a negative charge.
