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...

2. (3 Points) NMR spectroscopy could have been used to characterize the products in this experiment (we didn't use it because many of the products give spectra with overlapping peaks). NMR could have been advantageous, as the IR spectrum can give a false negative on the product if water or remaining carboxylic acid are in the product (presence of an...
