Exp 10: Preparation of benzil from benzoin Place 1 g of benzoin and 3 mL of concentrated nitric acid in a 50 mL beaker. Heat the mixture on a water bath for 15 minutes. At the end of this time, add 30 mL of cold water to the reaction mixture. Cooling the reaction mixture in ice-water bath will cause crystallization. Vacuum filter the product. Press the crystal gently with a clean glass stopper to remove as much of...

Can someone please help? Thank you.
ATOM ECONOMY: The traditional way of evaluating the efficiency of an organic reaction is to determine the percent yield of the reaction. Most organic chemists would be quite pleased with a reaction with >90% isolated yield of the target molecule. On the other hand, a yield of 30% is typically considered to be a disappointment. As a review of the concept of theoretical yield and percent yield, let's consider the following Sy2 reaction CH3CH2CH2CH2OH...
