3. (30 pts. total) We discussed the iodination of acetone in class. An alternative, but equivalent, way of writing the reaction is: acid H3C-C-CH3 + 131 acetone triiodide H3C-C-CH2 + 21 + H* iodoacetone iodide Is provides a more useful way to introduce 12 into the system. Iz is also useful because it absorbs visible light, and the rate of the reaction can be monitored by measuring the decrease in its absorbance at 565 nm. (Any time you can measure...
