Definitions from the WebPolar MoleculeDefinition:A polar molecule refers to a chemical compound or molecule that has a net dipole moment due to an uneven distribution of electron density. Senses and Usages:1. Chemistry:In chemistry, a polar molecule is formed when the electronegativity between the atoms in a compound is unequal. This unequal sharing of electrons leads to the creation of a positive and negative pole within the molecule. Example: Water (H2O) is a well-known polar molecule. 2. Biology:In biology, polar molecules play a crucial role in various cellular processes, including the movement of nutrients and waste across cell membranes Example: The hydrophilic heads of phospholipids in cell membranes are polar molecules. 3. Physics:In physics, polar molecules are important in areas such as quantum mechanics and molecular interactions. Example: Ammonia (NH3) is a polar molecule frequently used in studying molecular bonding. Sample Sentences:1. The polarity of a water molecule allows it to form hydrogen bonds with neighboring water molecules. 2. The polar nature of DNA's double helix structure facilitates proper base pairing. 3. The interaction between a polar molecule and a nonpolar molecule is weaker compared to polar-polar interactions. Related Products:Find related products on Amazon: | ||||
