5. The equilibrium constant (K) for the formation of methyl benzoate from methanol and benzoic acid at 25°C is 3.77. Use the equation for the equilibrium constant to calculate the theoretical yield of methyl benzoate for the following conditions. (6 marks) a) With equal initial amounts of the reactants (1 mole of each reactant) b) With a threefold (x 3) excess of methanol (1 mole of benzoic acid and 3 moles of methanol) 6.

4-chloro-2-methyl-2-pentene reacts with acetic acid (solvent), two substitution products are urmea, with the rearranged product predominating as shown in the diagram that follows. When small amounts of acetate ion are added to the reaction mixture, no increase in the rate is observed. Propose a mechanism that accounts for these results. Explain clearly why two products are formed (5 points) Minor Major

5. This reaction uses water as a solvent to efficiently prepare the Diels-Alder product, even though the reactants and products are not soluble in water. Explain what is meant by "hydrophobic effect" and how it is used in the context of this reaction. You may use the back side of this worksheet to answer the question. (4 pts) IC

2. Draw the structure of the byproduct that would be formed if the reaction mixture were not kept in an ice bath during the azo coupling reaction. [2 pts) Methyl orange can be synthesized using an azo coupling reaction, which is an example of an electrophilic aromatic substitution (EAS). In an azo coupling, the electrophile is an aryldiazonium salt, and the nucleophile is another electron-rich aromatic compound (typically an aniline or phenol). In this experiment, sulfanilic acid will be converted...

Question 30 3 pts How would the reaction respond if some PtO is removed from the reaction mixture at equilibrium? CS2(g) + 2H2O(g) + Pt(s) = C(s) + 2H2S(g) + PtO(s) ΔΗχη = -55 kJ The reaction would make reactants to reach a new equilibrium. The equilibrium position of the reaction would not be affected. The reaction would make products to reach a new equilibrium, D Question 31 3 pts The temperature of the reaction below is increased and once...

Experiment 7: Synthesis & Color Questions 1 A) Treat the reaction from Scheme 1 of the lab manual as an equilibrium reaction. What side of the equilibrium reaction is predicted to be favored if a significant amount of 2018 present in the solvent (1:1 H2O/EtOH solvent used and not EtOH)? (brief explanation) B) Someone will make a mistake and use the EtOH/H2O solvent instead of the 'pure EtOH solvent. Does your prediction in (A) match with the observable data of...
