In both cases, the conjugated bases are driven to share an electron pair with a proton in order to neutralize the negative charge. The negative charge of phenoxide is stabilized by resonance, a feature not enjoyed by cyclohexanoxide because it lacks a p system adjacent to the oxygen bearing the charge. There are two structural features that suggest a molecule might be aromatic. These p z orbitals form a continuous, closed loop. From this we conclude that phenol is probably aromatic.
Water is a two-electron ligand.
Like any atom, the iron ion prefers to have a full outer electron shell. For iron, that means having 18 valence electrons. Briefly explain your reasoning. In addition, Fe is in the middle of the transition metals and will therefore not easily have more than 18 electrons. Questions 9 and 10 refer to the carbohydrate shown below.
