Below is a reaction you will carry out in Chem 242. If you start with 100 mg of acetone, what mass of NaBH4 in mgdo you need?
Below is a reaction you will carry out in Chem 242. If you start with 100 mg of acetone, what mass of NaBH4 in mgdo you need? ОН - Mon) NaBH4 + 4 H20+4 B(OHz) + NaOH +4 To account for some of the NaBH4 decomposing, you plan to use 1.3 equivalents of it. Again assuming 100 mg of acetone, what mass of NaBH4 in mg do you need?
Question5 You will carry out the following reaction in this experiment. NaOH (aq) ethanol ?? acetone benzaldehyde dibenzalacetone To draw the reaction mechanism, what should be the first step? The acetone carbonyl O atom attacking the benzaldehyde csbonyl C The OH (hydroxide) attacking the benzaldehyde carbonyl C. The OH (hydroxide) deprotonating from the CH3 group in acetone The benzaldehyde carbonyl O deprotonating from the CH3 group in acetone.
