CH 3 CHOHCH 3. More complicated alkyl hydrogensulphates react with water in exactly the same way. At 220nm 100 AU max.

Could someone please explain all reactions happening in the tests especially for FA11. For test 3 I am not sure why they want us to add I2 until the solution turns orangered. C 3 H 8 O.
