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)...
