Respond to: When two atoms with distinctive electronegativity are linked to one another by covalent bond, the shared electron pair will not from the centre due to the difference in electronegativity. Such as, in hydrogen flouride molecule, flouride has increased electronegativity than hydrogen.
Remedy: Covalent bond could be formed because of the overlap from the orbitals belonging to The 2 atoms owning opposite spins of electrons.
