Question
Chemistry Question on coordination compounds
CO is a stronger ligand than Cl− because
A
CO is a neutral molecule
B
CO has π-bonds.
C
CO is poisonous.
D
CO is more reactive.
Answer
CO has π-bonds.
Explanation
Solution
CO is a strong ligand due to the presence of π -bonds, available for donating π -electrons to the metal-ion/atom. While, Cl− has pair of electrons but are less available for donation (due to more delocalised nature of π -electrons).
