1. If the temperature probe was mis-calibrated by +0.10 ˚C during both experimental procedure Part A and Part B, would the reported moles of biphenyl in the solution be too high, too low, or unaffected? Justify your answer . 2. Consider the following errors that can occur during Part B of the experiment. How would each of these errors affect the experimental molar mass of a solute (greater than true molar mass, less than true molar mass, unaffected)? Justify your answers. a. Some of the solid solute adhered to the side of the test tube during data collection. b. Some of the cyclohexane solvent vaporized during data collection. c. The solute dissociated slightly in the solvent.

You are carrying out an experiment by analysing alcoholic drinks by gas chromatography. Why is Gas chromatography the best technique used for this analysis? Why is Carbowax a suitable stationary phase for this analysis? What gases are used and what is their purpose and source?
1,4‐Dimethoxybenzene (0.642 g) was dissolved in 2.0 mL acetic acid in a 25 mL Erlenmeyer flask using heat from a hot plate. Once the solid dissolved, 1.0 mL tert‐ butanol was added, and the reaction mixture was cooled in an ice bath. Then 2.0 mL concentrated sulfuric acid was added in 2‐3 drop portions,stirring the mixture after each aliquot. After the addition, the flask was removed from the ice bath and allowed to sit at room temperature for 15 minutes. Then 1.0 mL water was added dropwise to dilute the acid and the reaction mixture was added to 40 mL cold water in a 100 mL beaker. The solid was vacuum filtered and washed with 5 mL cold water, giving 52 g filtrate. The product wasrecrystallized from 4.5 mL methanol, yielding 0.317 g purified 1,4‐di‐tert‐butyl‐2,5‐dimethoxy benzene (27.2% yield). What is the atom economy, e-factor, and effective mass yield?
