1)Draw the structure of only the Zaitsev product that would be obtained from the dehydration of 1- methylcyclohexanol. 2)Write out a detailed mechanism of the acid catalyzed dehydration of cyclohexanol. Use only hydronium as your acid source. 3)With respect to GC, what effect would raising the column temperature have on the retention time? 4)What would happen if you spiked your sample with a small amount of known cyclohexene and re-ran the GC?
