Which of the following double-bond bearing compounds is non-polar?

Question

Quizplus · Accepted Answer

In order to determine polarity, we need to look at the electronegativity difference between the atoms in the molecule. If the difference is 0, the molecule is non-polar. In molecule A, there are no identifiable atoms, so it is impossible to determine polarity. In molecule B, there is a C-O bond, which is polar due to the difference in electronegativity between carbon and oxygen. In molecule C, there are two C-S bonds, which have a difference in electronegativity of 0, making the molecule non-polar. In molecule D, there is a Cl-O bond, which is also polar. Therefore, the best choice for a non-polar compound is C (CS₂).
