Which of these molecules is polar?
A. BCI3
B. O₂
C. N2
D. NO

Answer i think u meant to write PCl3 instead of BCl3

:Taking the example of BCl3 and NH3, you have non-polar BCl3 (because of its flat geometry and symmetrical distribution of electrons) forming a polar non-covalent bond with the NH3 molecule (polar because of its tetrahedral geometry with a lone-pair of electrons attached to the nitrogen).

Polar molecules are SO2, CH2Cl2 and PCl3 are Polar molecules.

Explanation:

Water (H2O) is a polar molecule. ...  

Ethanol is polar because the oxygen atoms attract electrons because of their higher electronegativity than other atoms in the molecule.  

Ammonia (NH3) is polar.

Sulfur dioxide (SO2) is polar.

Hydrogen sulfide (H2S) is polar.
