Asi las moleculas diatomicas homonucleares o2, cl2, n2 son siempre apolares. Moleculas polares y no polares by tina namba on prezi. Molecular polarity bond polarities originate from bonds between atoms of different electronegativity and molecular polarities result from the sum of bond polarities.

Y cualquier estructura molecular formada por atomos con electronegatividades muy parecidas sera apolar por electronegatividad como sucede con las moleculas homodiatomicas como h 2, cl2, o 2, etc. Polar and nonpolar bonds in homonuclear diatomic molecules such as h 2 or cl 2 electrons are shared equally between equal atoms. In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole moment, with a negatively charged end and a positively charged end polar molecules must contain polar bonds due to a difference in electronegativity between the bonded atoms.
