CClF3 is polar because it is asymmetrical. Imagine the central carbon atom inside a tetrahedrom with the base of 3 flourines and the top of a chlorine. Since the flourines are more electronegative than the chlorine (F is higher in the VIIA column than Cl), they will get the bigger share of the electrons, and Cl less. So the fluorine side is d- and the chlorine side d+. It is hard to draw on this, but this is my best:
Cl d+
C
F F F d-

There are two isomers of Ethenediol. One is polar and the other is nonpolar.
It's ionic, not polar
yes. yes it is.

Cl4 does not exist, but if CCl4 is meant: this is a nonpolar compound
It is nonpolar
