(a) Predict the UV maximum for the reactant and product of the following photochemical reaction: CH3, CH3 hv CH; CH; CH3 CH CH CH3 `CH3 (b) Is UV spectroscopy a good way to distinguish the reactant from the product? (c) How would you use infrared spectroscopy to distinguish between the reactant and the product? (d) How would you use proton NMR to distinguish between the reactant and the product (two ways)? (e) How could you distinguish between the reactant and the product by using DEPT NMR (see Chapter 9)?
