True.
Polar substances have electronegativity differences while non polar substances do not have differences.
The analyze is:
N2F2 is polar. Because there are differences in the electro negativity values of the 2 elements. But the polarity depends on the type of isomer, the cis isomer form is polar because it has a dipole moment of 0.16 D. Meanwhile the trans isomer form is non polar because it doesn't have a dipole moment.
