Solution:

Greater the electronegativity difference more is the polarity of the covalent bond formed by the elements. Electronegativity of N is approximately equal to Cl. Thus N-Cl and N-N bonds are almost non-polar. Out of O-F and N-F, N-F bond is more polar as electronegativity of N is less than O and F is most electronegative
