Question

The Material Safety Data Sheets (MSDS) for all the chemicals involved in this lab are on iLearn. Read these and answer the following questions: Which chemical is the most dangerous in this lab? Explain why you chose your answer for part a), and the safety precautions you will take when handling this material. Fill in the reaction table below. Make sure you correctly calculate the molar amounts of your reactive materials. Calculate the Theoretical Yield of your product, i.e. the mass you would expect to recover (assuming 100% conversion to product). Distinguishing between the products A, B and C is quite challenging by IR spectroscopy alone -explain the differences and similarities that you would expect to see in the corresponding IR spectra.

Explanation / Answer

Moles = amount/molar mass of the compound

1mol = mmol *10^3

mmol of D-carvone = 0.72g/150.22g/mol =4.79 *10^-4 mol = 4.79 *10^-1 mmol

------------------------------------------

mmol in 6 M aq NaOH = 1mL * 6M = 6 mmol

-------------------------------

30% aqueous H2O2 contains 30 g H2O2 in 100gm solution.

100gm water = 100mL water

mass of H2O2 in 1.5 mL = 30g *1.5mL/100mL = 0.45 g

moles of h2O2 in 1.5mL = 0.45g/34g/mol =0.0132 moles = 13.2 mmol

----------------------------------

density of methanol = 0.7913 g/mL

mass of methanol = 8mL * 0.7913 g/mL= 6.33 g

moles of methanol = 6.33g/32g/mol = 0.1978 mol = 197.8 mmol
