Question

Which of these molecules are polar? check all that apply. co2 so2 ch2cl2 pcl3?

Answer 1

Polar molecules are molecules with net dipole due to the presence of partial positive and partial negative charge. For example, water is a polar molecule that has partial positive and partial negative charge on it. CO2 is a non polar compound.

Answer: The following molecules are polar:
SO2- It is polar because it has dipole moment.
CH2Cl2
PCl3

Answer 2

SO2 and PCL3 are all polar. SO2 is polar because it is a non-linear molecule and is slightly more charged on each side. PCL3 is polar because because the dipoles don't completely cancel each other out.
