The compound between vanillin and isovanillin that would have a π → π ∗ UV absorption at the greater λ max when the compound is dissolved in NaOH the solution is to be identified. The explanation for the corresponding answer is to be stated. Concept introduction: Spectroscopy method is used to identify the structure of the molecule. It is based on the interactions between matter and electromagnetic radiations. Molecules have bonding or non-bonding electrons that can absorb light while promoting electrons from the ground state (HOMO) to an excited state (LUMO). The light absorbed is usually in the UV or visible region. Conjugation in the molecule also affects the wavelength of light absorbed.
