Calculate the mass and volume of 150 mmol of benzaldehyde, and the theoretical yields of benzoin, benzil, and benzilic acid expected from that much benzaldehyde. I'm pretty sure that you use 2 mol of benzaldehyde per 1 mol of the other compounds, but you might want to check to make sure. Please calculate the theoretical yield in grams. Thank you very much.

Expt 55 Micro: Borohydride Reduction of a Ketone: Hydrobenzoin from Benzil 3. Sodium borohydride can be used in ethanol solutions to rapidly reduce aldehydes and ketones at room temperature. Even though lithium aluminum hydride (LiAlH4) is much more reactive than sodium borohydride (NaBH4) it can’t be used to reduce aldehydes and ketones in ethanol solutions. Explain why not? NOTE: The answer is not the quote from the lab book “Unlike lithium aluminum hydride, sodium borohydride is insoluble in ether and...
