JEE Main Chemistry question

Which statement about the coordination number of a cation is true?

(A)Most metal ions exhibit only a single characteristic coordination number
(B)The coordination number is equal to the number of ligands bonded to the metal atom
(C)The coordination number is determined solely by the tendency to surround the metal atom with the same number of electrons as a rare gas
(D)For most cations, the coordination number depends on the size, structure and charge of the ligandsCorrect

Answer: (D)

Solution

Coordination number is influenced by steric (ligand size) and electronic (charge, field strength) factors of both
