how would you define a "pure covalent bond"

in the bonding chapter of my textbook, a covalent bond is defined as " the strong electrostatic attraction between a shared pair of electrons and the nuclei of the bonded atoms"

the electronegativity and polarity chapter of my textbook says the bonding in oxygen, hydrogen and chlorine is a "pure covalent bond" because the bonded atoms come from the same element and the electron pair is shared equally. If you were asked for a definition of a "pure covalent bond" what would you put?

also how would you define a "polar covalent bond"

what's the difference between a normal covalent and pure and polar covalent bonds, or are pure and polar covalent bonds just "subsections" of a covalent bond?

thanks in advance.

Pure covalent bonds require that both the atoms in the molecule are the same and hence have equal electronegativity.

Polar covalent bond is every other one.

Pure covalent is one extreme of the bonding spectrum from the other extreme, ionic bonding.

Pure covalent - polar covalent - distorted ionic - pure ionic

thank you

what's a distorted ionic bond? and could you give an example pls

mgcl2 is an example. It is part ionic, partly polar.
