The theoretical yield of 1,2-epoxycyclohexane is _grams, when starting with 3.0 grams of trans-2- bromocyclohexanol. (Enter the number using 3 significant figures, i.e. 1.22) Given: 3.0 g of trans-2-bromocyclohexanol FW: 179.05 25 mL of 10% NaOH FW: 40 and density: 1.11 g/mL 1,2-expoxycyclohexane FW: 98.15 Hint: Identify the limiting reactant (NaOH or trans-2- bromocyclohexanol) by calculating the number of moles of each. For 1 mole of limiting reactant, 1 mole of product is formed. Use the # of moles and the molecular weight of the product to calculate the theoretical mass (yield).

Suppose that at the end of the experiment, 1.45 g of 1,2- expoxycyclohexane was obtained. This would account for _% yield. (Enter the value using 3 significant figures, i.e. 94.2) note: Use the theoretical yield calculated in the previous question.

At the end of the second lab period an IR spectrum of the product, 1,2-epoxycyclohexane, was obtained as shown: Write a brief conclusion (3-4 sentences) to comment on how IR is used to characterize the product. You may wish to compare the IR of the starting material from Parts A and B (weeks 1 and 2).
