Coordinate Covalent Bond

Postby Trent Yamamoto 2J » Sun Nov 03, 2019 11:40 pm

Does a coordinate covalent bond only occur with Lewis acids and Bases? (I know Boron Trifluoride was given as an example)

A coordinate covalent bond is different from a covalent bond, because instead of both atoms each sharing one electron to form a bond, there is only one atom that donates two of its electrons to form a bond. Coordinate covalent bonds do not just occur in Lewis acids and bases, and could also be found in metal ligands. For example, NH3 + Ag+ forms the bond [Ag-NH3]+, where the Nitrogen's 2 lone electrons are utilized to form a coordinate covalent bond with the Silver ion.

I think the term Lewis acid or base only describes the atom or molecule that gives or receives the electrons. So even metal cations are considered lewis acid.
