1)Calculate the % atom economy for the following two methods for converting benzene, C6H6, to aniline, C6H5NH2.
Method 1: C6H6 + (CH3)3SiN3 + 2 F3CSO3H + NaOH
? C6H5NH2 + N2 + (CH3)3SiOSO2CF3 + NaF3CSO3 + H2O
Method 2: C6H6 + HNO3 ? C6H5NO2 + H2O
C6H5NO2 + 3 H2 ? C6H5NH2 + 2 H2O

2)A 0.2527-g sample of a mixture of Mg(OH)2 and Al(OH)3 was treated with 50.00 mL of 0.225 mol L?1 HCl(aq). The resulting solution required 13.73 mL of 0.176 mol L?1 NaOH(aq) to neutralize the excess, unreacted HCl. What was the percentage by mass of Mg(OH)2 in the original sample? [Hint: When Mg(OH)2 or Al(OH)3 reacts with HCl(aq), the products are a chloride salt, water and CO2(g). Assume that all of the CO2(g) leaves the solution without reacting.]

3)
When a 0.6333-g sample of a compound of carbon, hydrogen and sulfur was burned in excess oxygen, 0.9272 g CO2, 0.3795 g H2O and 0.6749 g SO2 were obtained. In a separate experiment, it was found that, for fixed temperature and pressure, a 0.100 L sample of this compound takes 1.97 times longer to effuse than does a 0.100 L sample of Ar(g). What is the molecular formula of the compound? , draw possible structures for the molecule (1 bonus mark for every acceptable structure, up to a maximum of 5 bonus marks).

4)
Blood alcohol content (BAC) is often reported in weight-volume percent (w/v%). For example, a BAC of 0.08% corresponds to 0.08 g CH3CH2OH per 100 mL of blood. In Ontario, and the rest of Canada, the maximum legal BAC for fully licensed drivers is 0.08%. Estimates of BAC can be obtained from breath samples using a number of commercially available instruments, including
