20 questions
Question 1: Pyridine is solely a σ-donating ligand without any π-accepting character.
A. Ano
B. Ne
Explanation: The study materials indicate that pyridine (py) is a σ-donating ligand and is also weakly π-accepting.
Question 2: Fischer carbene ligands are exclusively σ-donating.
A. Ano
B. Ne
Explanation: Fischer carbene ligands exhibit both σ-donating and π-accepting bonding characteristics.
Question 3: Ethylenediamine (en) is capable of both σ-donating and π-donating electrons to a central metal atom.
A. Ano
B. Ne
Explanation: The study materials state that ethylenediamine (en) is σ-donating only, which means it does not also exhibit π-donating properties.
Question 4: A Schrock carbene ligand exhibits both σ-donating and π-accepting bonding characteristics.
A. Ano
B. Ne
Explanation: The Schrock carbene ligand is described by its modality as σ-donating and π-accepting.
Question 5: The Aqua ligand contributes 2 electrons.
A. Ano
B. Ne
Explanation: The study materials indicate that Aqua (H₂O) has an e- count of 2.
