Predict whether each of the following molecules is polar or non-polar:a) IF, b) CS2, c) SO3, d) PCl3, e) SF6, f) IF5.

Answer;

Polar: IF, PCl3, IF5

Nonpolar: CS2, SO3, SF6

Explanation: Polar molecules form when two atoms do not share electrons equally in a covalent bond. A molecule is classified as a polar molecule when the arrangement of the atoms is such that one end of the molecule has a positive electrical charge and the other end has a negative charge. A non-polar molecule does not have electrical poles. The electrons are distributed more equally. Therefore, a non-polar molecule does not have a profusion of charges at the opposite ends. The majority of hydrocarbon liquids are non-polar molecules.
