JEE Main Chemistry question

Which of the following is not true for a ligand-metal complex?

(A)A highly charged ligand forms a stronger bond
(B)The greater the ionization potential of the central metal, the stronger the bond
(C)The larger the permanent dipole moment of the ligand, the more stable the bond
(D)The larger the ligand, the more stable the metal-ligand bondCorrect

Answer: (D)

Solution

Larger, more diffuse ligands generally give *poorer* orbital overlap with the compact metal -orbitals, weakening (not strengthening) the metal–ligand bond and lowering the crystal field splitting — so statement (D)
