The abnormality of HF is due to the presence of hydrogen bonding. They are covalent substances soluble in polar solvents. The bond strength of HX decreases down the group as the bonds become less polar. This property governs the reactivity of the halides.
Polar covalent bonding. In most covalent compounds [compound: A compound is a substance formed by the chemical union (involving bond formation) of two or more elements.] the bonding is polar covalent. Covalent bonds with unequal electron sharing are called polar covalent bonds.hen two atoms bonded by a covalent bond have the same electronegativity the electrons will be equally shared. This is called pure (non-polar) covalent bonding. For example, the chlorine molecule, Cl 2.
