Question

F2 is non polor molecule while HF is polor molecule why?​

Answer 1

Answer:

This is because F is more electronegative than H, and therefore F attracts the electrons of H to itself. This results in a polar bond. As the bond dipoles is not arranged symmetrically, it is not a polar molecule. H2 and F2 is non-polar as they are made of two same atoms which means both atoms should have the same electronegativity. Thus, an equal number of electrons exist in the orbital overlap, and thus H2 and F2 is non-polar.
