Dichloromethane and sodium hydroxide reaction
WebInitially, the 1.0001g of benzil was a yellow powder, and once dissolved in the 5mL dichloromethane and 5mL ethanol, became a clear yellow solution. The later addition of 0.2998g sodium borohydride caused the solution to become cloudy. As the reduction reaction of benzil progressed, the solution became less cloudy. A TLC plate determined …
