Next, you have to examine the net partial charges. If there is a net partial charge, the molecule is polar. If not, it is nonpolar. " - How do you tell if a molecule is polar

How do you tell if a molecule is polar

WebWhen you place a molecule with an electric dipole in an electric field, a force acts to turn the molecule so that the positive and negative ends line up with the field. The magnitude of the turning force is given by the formula µ = q × d where q is the amount of charge and d is the distance between the two charges. µ is the turning moment. WebHow do you know if a compound is polar? A molecule is polar if one part of it has a partial positive charge, and the other part has a partial negative charge. When in a bond, atoms can either share electrons (covalent) or give them up (ionic). The atom that holds the electrons closer will thus be more negatively charged than the other atom.
