Question

How is a complex ion a Lewis adducts?

Step-by-Step Solution

Answer

Complex ions are Lewis adducts because they are formed from Lewis acids (the central atoms or central ion) to which Lewis bases (ligands) attach to.

Step 1: Definition of Coordination Compound

A coordination complex consists of a central atom or ion, which is sometimes metallic and is termed the coordination centre, and a surrounding array of bound molecules or ions, that are successively called ligands or complexing agents.

Step 2: Solve the given statements

When a Lewis base and a Lewis acid react and form a compound, this compound is termed Lewis adduct. Lewis adducts contain coordinate covalent bonds where the electrons within the bond come from the Lewis base. Complex ions are Lewis adducts because they're formed from Lewis acids (the central atoms or central ion) to which Lewis bases (ligands) attach to.
