NCl3 could be considered nonpolar because nitrogen and chlorine have nearly the same electronegativity.
it is a pyramidal molecule and chlorine is slightly more electronegative than nitrogen due to three chlorine atoms this is a polar molecule.
nonpolar or polar
polar covalent
Assuming you are referring to nitrogen trichloride, then it IS polar, it is NOT chiral though. NCl3 has C3V symmetry and therefor is polar. The molecule is NOT planer due to the lone pair on Nitrogen so the bond dipoles do NOT cancel thereby making it Polar.
Nonpolar
non polar
yes
There are two isomers of Ethenediol. One is polar and the other is nonpolar.
It's ionic, not polar
yes. yes it is.
It is non polar
nonpolar
Cl4 does not exist, but if CCl4 is meant: this is a nonpolar compound
