  • The Se=C=Se molecule is non-polar because

    A
    the bonds in the molecule are all non-polar
    B
    the bonds in the molecule are polar but their effect on the overall polarity is cancelled by the effect of lone pairs in the valence shell of the carbon atom
    C
    the bonds in the molecule are polar but their effect on the overall polarity is cancelled by the fact that they are equal in magnitude and oppositely directed
    D
    the bonds in the molecule are polar but the polar effect is cancelled by the resonance hybrids which distribute the charge evenly.
