12 out of 13
Which of the following choices represents the vectors of bond dipoles of the indicated (indicated by the arrows) bonds of the compounds A & B, respectively?
Ans. C For Compound A, we should compare the atoms involved in the bond in question. Chlorine is more electronegative than boron. This rules out Choices B and D. For Compound B, the bond dipole should be directed toward the carbon atom. This rules out Choices A and D. So the only choice which has not been ruled out is C.
