- I recovered 3 mL of cyclohexene, how many grams of water was produced in the reaction please show how? Cyclohexanol can attack the carbocation intermediate formed during the synthesis of cyclohexene. Draw this side product with the molecular formula C12H22O. Please ASAPPPP you guys didn't answer the last oneAssuming a 56.8% yield, how kany ml of alkene is required to produce 22.5 mL of 2,3-dimethyl-2-butanol? MW of alkene: 84.16, d: 0.653 MW of 2,3-dimethy-2-butanol: 102.17, d:0.823Need help on last question. The reaction is a fisher esterification. My unknown ester is pentyl acetate (amyl acetate) and my unknown alcohol is 1-pentanol. 1.5 mL of 1-pentanol used giving us 0.013806 moles used. 3.0 mL of acetic acid used giving us 0.052604 moles used. Please show all work (including identification of limiting reactant)
- From the table of available reagents select the one(s) you would use to convert:3-pentanol to 3-bromopentane:cyclopentanol to trans-2-methylcyclopentanol:Use the minimum number of steps; in no case are more than four steps necessary.List reagents by letter in the order that they are used; example: fa.1pentanol + NaBr/H2SO4 -> 1-bromopentane Limiting reagent: 1-Pentanol Percent Yield: 64.5% The typical yield for this reaction is about 80%. Compare this to the yield attained..What issues might account for the yield being lower than expected?What is the limiting reagent, and their ratios to each other?
