Critical Thinking Questions 1. Draw the structure for the product from the reaction of 1,3-cyclohexadiene and maleic acid (cis-2-butenedioic acid). 2. What is the product expected from the reaction of 1,3-butadiene and 3-sulfolene? Why is this not a major concern as a by-product? Part B, the dimer dicyclopentadiene is a possible contaminant of cyclopentadi- ene. It is also a diene. Can dicyclopentadiene undergo reaction with cyclopentadi- ene? Can dicyclopentadiene act as a diene and undergo reaction with the anhydride 3....

4-aminophenol (1.0 g) was dissolved in an inert organic solvent. Pyridine (1.50 mL) and acetyl chloride (1.40 mL) were added, and the reaction was stirred until determined to be complete by TLC. Afteworkupup and purification, you isolated 1.40 g of a product. The experimental melting point was 155 oC, and mass spec analysis indicated that the molecular weight of this product is 193.20 g mol─1. What is the structure of the isolated product? Suggest a specific procedural modification that would...

If cyclohexanol(mw 100) (d=0.8 g/ml) were substituted for 2-methylcycholhexanol, only one product, cyclohexane (d=0.8 g/ml) would be obtained. Distillation of the reaction mixture would occur at 85 C. Assume that the vapor pressures of cyclohexane and water are 152 mm and 608 mm respectively at 85 C. If 0.6 mol of water are obtained in the distillate what is the yield of cyclohexane? Assume that the bp of cyclohexane is 100 C and that cyclohexane is insoluble in water? a)...
