What covalent bond is called a covalent polar bond? Give two examples of compounds with a covalent polar bond. How does the common electron pair shift during the formation of a covalent polar bond? Which of the atoms acquires a partial positive charge, and which acquires a partial negative charge?
In the case when the common electron pair is mixed towards one of the atoms, the covalent bond is called non-polar, for example, in H2O, HCl2, NH3, CO2.
With the formation of a covalent polar bond, the total electron pair is displaced to an atom with a greater electronegativity, and a partial negative charge arises on this atom, and a partial positive charge on a less electronegative atom.
