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.

Part II. Competing nucleophiles with t-butyl alcohol 1. The composition of the product mixture is analyzed based on refractive index measurem. At 20.0 °C, the refractive index of puret-butyl chloride is 1.3877 and that of pure 1-buty bromide is 1.4280. One previous student determined the refractive index of his product mixture to be 1.4250 at 20.0 °C. Assume a linear relation between the refractive index and the molar composition of the mixture. Calculate the molar percentages of t-butyl chloride and/-butyl...

Introduction Alkyl halides can be prepared from alcohols by reactions with hydrogen halides (HCI, HBr, or HI) via nucleophilic substitution. In this type of reaction, the nucleophile displaces a leaving group from a carbon atom of an organic substrate (here the alcohol once protonated). Both electrons of the new bond to the carbon are provided by the nucleophile while the...

CONTEXT So we did an Sn1 reaction in chem lab to convert t-butyl alcohol to t-butyl chloride by the following reaction C4H10O + HCl --> C4H9Cl + H2O We did this by mixing the HCl and the t-butyl alcohol in a separatory funnel, then we collected the organic layer that formed and vacuum distilled the product. QUESTIONS What is something that could cause a low yield in this experiment? we got a 26% yield, I was thinking maybe heating up...
