STANDARD Chemistry Ligands MCQ Question
Ammonia acts as a very good ligand but ammonium ion does not form complexes because
NH₃ is a gas while NH₄⁺ is in liquid form
NH₃ undergoes sp³ hybridisation while NH₄⁺ undergoes sp³d hybridization
NH₄⁺ ion does not have any lone pair of electrons
NH₄⁺ ion has one unpaired electron while NH₃ has two unpaired electrons.
Correct Answer
Detailed Explanation
NH₄⁺ does not have any lone pair of electrons, which is necessary for forming coordinate bonds in complexes, unlike NH₃ which has a lone pair.
