Introduction The purpose of this experiment was to investigate the method of dehydration of organic compounds. With the starting material being cyclohexanol and the product being cyclohexene, the mechanism of the reaction was explored and understood- thus, the idea of an elimination reaction was discovered and considered.

Then, 12 mL of 85%
