CHCL3 is polar. all the other ones arent.
CO2 and CCl4 arent because the molecules are symmetrical.

Hey, this is actually quite simple if you have an electronegativity chart!
Okay... so you take EN (electronegativity of the first element and subtract it from the first element)
Example :
CO2
Electronegativty of Oxygen - Electronegativity of Carbon.
If your answer is any of these ... it is polar
Slightly polar bond: 0.5-0.9
Moderately polar bond: 1-1.3
Highly polar bond: 1.4-1.7
Here is a list of the electrogenativity values for every element by the way :

Good luck... hope it helped.

Carbon tetrachloride and chloroform are formed using covalent bonds, while carbon dioxide, nitrogen, and oxygen are formed using ionic bonds.
Chemicals formed using ionic bonds will be polar.

xcept N2 and O2,all are polar.
