5. Examine the attached 'H NMR spectrum of the product that you are making today. What significant difference(s) are present (with respect to the spectrum of the dibromide product)? 6. For today's experiment, we are doing a reaction with trans-cinnamic acid using NBS (which effectively provides a dilute solution of bromine) in a mixture of water and methanol. Predict the four possible products of this reaction. Note the dibromide product is not a possibility here. (See question 2). For this...

3. A solution of KOH was standardized using KHP. A 6.245 g sample of KHP required 41.05 mL KOH in one titration and 40.85 mL in the second. Calculate the average molarity of the KOH solution. 4. 2.500 g of KHP were used to standardize a calcium hydroxide solution. Write the equation for the reaction that occurred. If 20.00 mL of Ca(OH), were required in one trial what is the molarity of...
