The term 'polarity' refers to a separation of electrical charge. This chapter examines how this separation can come about and its consequences in molecules.
A covalent bond is formed by the electrostatic attraction between a shared pair of electrons and the positively charged nuclei.
Bond polarity results from the difference in electronegativities of the bonded atoms.
Applications and skills
Deduction of the polar nature of a covalent bond from electronegativity values.
