How can the bonds between B and N be polar while the compound B3N3H6(inorganic benzene) is non polar?

Question

How can the bonds between B and N be polar while the compound B3N3H6(inorganic benzene) is non polar?

In: Chemistry

Answer 1

A single B-N bond is polar because the significant difference in their electronegativity causes the compound to form the positive-negative poles on the molecule. However B3N3H6 is a ring structure where the electronegativity is evenly distributed around the molecular structure so there is no polarity.
