How do you classify bonding type according to electro-negativity differences

Chemical bonding cannot be solely explained with the concept of electronegativity. According to generality, it is said that a particular compound has a principal ionic character if it exceeds the electronegativity difference of 1.7 in Pauling's scale.

Pauling's definition of electronegativity Electronegativity is defined as the attracted force which an atom, bonded by a covalent bond, exerts on the bonded pair of electron responsible for the covalent bonding.

If this difference is under 2 the bond is covalent; if the difference is over 2 the bond is ionic.

The bonding atoms/ions should have different values in electronegativity.
Not sure about your examples but electronegativity variance is a good rule of thumb for deciding ionic from covalent bonds. Electronegativity variance less than 1.4, generally much less, indicates a covalent bonding. Electronegativity variance greater than 1.4 indicates ionic bonding.
FON The atoms that hydrogen bonds to when hydrogen bonding occurs, due to electronegativity variance, are; Fluorine Oxygen Nitrogen
To say that bonding is on a continuum means that the type of bonding changes gradually as the difference in electronegativity between atoms increases. There is no sharp distinction between polar covalent and ionic bonds.
Rochow electronegativity is based on the effective nuclear charge of an atom and by extension the attraction a valence electron feels to the nucleus. Pauling electronegativity is based on bonding energies and states that the heteroatomic bond A-B's dissociation energy should be an average of the homoatomic bond A-A and B-B's dissociation energies. Any additional energy differences will be a result of electronegativity. Aside** Muliken electronegativity is an average of the ionization energy and electron affinity of a gas phase atom. All 3 electronegativities increase going up and to the right on the periodic table.
According to Pauling's scale, hydrogen has an electronegativity of 2.1 and Cl has 3.0. This difference makes the H-Cl bond polar by the attraction of bonding electrons towards chlorine.
