Coordinate covalent bond difference

[Manav Patel 3L]

What defines a coordinate covalent bond, and how does it differ from a regular covalent bond?

A coordinate covalent bond occurs when both electrons in the shared pair come from the same atom. In other words, one atom provides both electrons for the bond. This typically happens when one atom has a lone pair of electrons that it shares with another atom lacking electrons. On the other hand, a regular covalent bond, or simply a covalent bond, forms when each atom contributes one electron to the shared pair. Both atoms share the responsibility of providing electrons to create the bond. In summary, the key difference is in the source of electrons: a coordinate covalent bond involves one atom donating both electrons, while a regular covalent bond involves each atom contributing one electron to form a shared pair.
