The Correct Option is B

Solution and Explanation

Effective atomic number EAN = Atomic number - oxidation number $+$ $2 \times$ coordination number For $\left[ Al \left( C _{2} O _{4}\right)_{3}\right]^{3-}$ $Z=13$ $ON =3$ $C N=6$ $\therefore$ EAN $=13-3+2 \times 6=22$

Concepts Used:

Coordination Compounds

A coordination compound holds a central metal atom or ion surrounded by various oppositely charged ions or neutral molecules. These molecules or ions are re-bonded to the metal atom or ion by a coordinate bond.

Coordination entity:

A coordination entity composes of a central metal atom or ion bonded to a fixed number of ions or molecules.

Ligands:

A molecule, ion, or group which is bonded to the metal atom or ion in a complex or coordination compound by a coordinate bond is commonly called a ligand. It may be either neutral, positively, or negatively charged.
