Question

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

In: Chemistry

Answer 1

So the individual B-N bonds are polar but because of the ring shape of the molecules all of the dipoles cancel out the fields from the others. If you draw vector lines and sum them you will find they all add to zero.
