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.
