Polarity of Molecules

Polarity of molecules refers to how electrical charge is distributed within a molecule. If electrons are shared equally between atoms, the molecule is nonpolar, meaning no distinct positive or negative regions. If electrons are shared unequally, the molecule becomes polar, with areas that have slight positive or negative charges. This uneven charge distribution affects how molecules interact, such as why water (polar) mixes well with other polar substances, while oil (nonpolar) does not. Polarity influences a molecule’s physical properties, solubility, and behavior in different environments.
