is h2o polar or nonpolar?
In general, a bond between two atoms with an χ difference of 0.4 to 1.7 (on the Pauling scale) is considered polar covalent. Polar molecules have a non-zero net dipole moment. Both CO2 and H2O have two polar bonds. ... The polar bonds in the bent H2O molecule result in a net dipole moment, so H2O is polar.
