EXPERIMENT 8: SUPPLEMENTARY LAB QUESTIONS 1. Would you expect benzoic acid or anisole to be a more effective coupling reagent? Why? Anisole would be more effective coupling agent reagents than benzoic acid because anisole has o-cH₃ an electron donating group whereas benzoic acid have a 2-oh group attached to the benzene ring that acts as electron withdrawing group. 2. Most diazo coupling reactions do not work well in acidic solutions. Explain. 3....

Experiment 9 Acid-Base Extraction Liquid-liquid extraction utilizes the contrast solubilities of solutes in two immiscible solvents the separation of a mixture. An extracting solvent can be reactive that changes the character of solute. Consider a mixture of organic acid, organic base, and neutral substance, for example, benzoic acid, aniline, biphenyl, nd phenol. They sodium benzoate. Sodium hydroxide changes phenol to sodium phenoxide. Hydrochloric acid changes aniline to...

2. A solution containing a mixture of naphthalene, benzoic acid, and benzaldehyde is analyzed via TLC and GC. Use the structures and properties of the compounds to aid in answering the following questions. A. In the TLC experiment, the mixture is spotted on a silica TLC plate and eluted with a 1:1 mixture of hexanes and ethyl acetate. Three spots are observed on the plate, with Re values of 0.25, 0.58, and 0.74. Indicate which spot corresponds to which compound....

Question 3 1 pts If compound A elutes (comes off) a GC column earlier than compound B in a temperature gradient GC run. What can be inferred about their respective boiling points? Compound A probably has a lower boiling point than that of compound B. Compound A and B have the same boiling point. Elution time does not correlate...

E AFTER COMPLETING LAB. ANSWER IN SPACE PROVIDED. Suppose the heat of neutralization had been determined using a glass beaker instead of a polystyrene coffee cup How would the measured value have been affected? The heat of combustion of octane, C,H,. can be measured in a way similar to the method youC used to measure the heat of neutralization. The bomb calorimeter is used instead of a coffee cup. The reaction is 2C,H,1)+ 25 O, (g) 16 CO, (g) +...

Post-lab Exercises : Say, for example, that you had prepared a Buffer C, in which you mixed 8.203 g of sodium acetate, NaC2H302, with 100.0 mL of 1.0 Macetic acid. 1. What would be the initial pH of Buffer C? (5 pts) 2. You add 5.0 mL of 0.5 M NaOH solution to 20.0 mL each of Buffer B (from your experiment) and Buffer C. Which buffer's pH would change less? Explain. (5 pts) 3. What would be the final...

5. For today's experiment, you will be performing the first step of your multistep synthesis to make trans- 1,2-cyclohexanol from hexanol. You will be using distillation to separate the product of the first step in the synthesis. (see the procedure below for diagrams and photos of what distillation setup looks like. Check the boiling points provided in the chemical table for starting material and product. Which compound boils at a lower boiling point? Explain briefly based on boiling point differences...
