Science / Chemistry / Polar Molecule: An asymmetric molecule containing polar bonds. H2O, NH3, and hcl are examples of polar molecules. Non-examples are CO2, ccl4, and bcl3 which contain polar bonds but are nonpolar because they have symmetric shapes. Alkanes are usually asymmetric but are nonpolar because they contain no polar bonds. Polar molecules are electric dipoles and they attract each other via dipole-dipole forces.
Polar Noun Synonyms: Arctic, Antarctic, frigid, icy, glacial, freezing, frozen, numbing, Siberian, hibernal, hyperborean, brumal, wintry
