Synthesis of Cyclohexene The Dehydration of Cyclohexanol.
Dehydration of Cyclohexanol Organic Chemistry 1 Lab Abstract: The goal of this experiment was to dehydrate cyclohexanol to form an alkene product, or more specifically cyclohexene. Then an IR spectroscopy and a classical bromine chemical test were performed which verified that there was indeed formation of a cyclohexene product. Reagent Table.
Cyclohexanol is easily oxidised to cyclohexanone, and if subjected to more robust conditions, will undergo a ring-opening oxidation, and oxidation of the two ends of the molecule forms the substance known as adipic acid. Adipic acid, when reacted.
In chemistry, a dehydration reaction is a conversion that involves the loss of water from the reacting molecule or ion. Dehydration reactions are common processes, the reverse of a hydration reaction.Common dehydrating agents used in organic synthesis include sulfuric acid and alumina.Often dehydration reactions are effected with heating.
Based on the calculation, the percentage yield obtained was 42.819% First, one must write out the balanced equation the preparation of cyclohexene from cyclohexanol: The equation shows that one reactant produces one product (water is also a product but we are only interested in the cyclohexene here) in a 1:1 ratio.

Dehydration of cyclohexanol College: The experiment was carried out using a distillation flask. An efficient dehydrating agent was employed. The dehydrating agent was to remove the OH group from the cyclohexanol leading to the formation of cation as the intermediate product and thereafter remove a hydrogen atom from the cation resulting in the formation of cyclohexene.
When the leaving group is a water molecule, the elimination is known as a dehydration reaction, as shown below. Goal: The goal of this week’s lab is to synthesize cyclohexene from cyclohexanol using the method of dehydration. You will then test for the presence of the carbon-carbon double bond by the addition of aqueous bromine and.
