Worked Solution & Example Answer:Which is not a correct statement? A - AQA - A-Level Chemistry - Question 7 - 2017 - Paper 3
Step 1
C. A ligand accepts a pair of electrons from a transition metal
Answer
This statement is actually correct; however, it is phrased to imply that the ligand acts as a donor, accepting electrons from the transition metal. In reality, ligands donate a pair of electrons to form coordinate bonds with transition metals. Thus, while the wording may cause confusion, it does not accurately describe the function of ligands in coordination chemistry.
