What short chemical test could you make on the product to indicate whether cyclohexene is present or absent?
Addition of aqueous bromine can test the solution for the presence of an alkene (cyclohexene).
How cyclohexene mignt be formed as a byproduct in the synthesis of cyclohexanone?
One of the common ways to synthesize ketones is by oxidizing secondary alcohols. Cyclohexanone can be easily prepared from cyclohexanol (or hydroxycyclohexane - same thing) by allowing cyclohexanol to react with potassium dichromate (K2Cr2O7) in the presence of acid. However, some of the cyclohexanol will undergo an elimination reaction because of the acid present and form cyclohexene. Your question is a good example of why it is often important to consider how the reactants should be mixed to get the best results. You would not want to add all of the cyclohexanol to the dichromate solution since performing the reaction that way would maximize the percentage of cyclohexene formed. To limit the extent of the competing elimination reaction, one would want to: 1) Look up the oxidation of secondary alcohols to ketones using potassium dichromate in the literature in order to a. determine the amount of acid needed, and don't use more acid than is necessary, and b. try to find the optimum temp. at which to carry out the reaction. The lower the acid concentration, the less cyclohexene that will be formed. 2) Slowly add the alcohol to a rapidly stirring mixture of an aqueous solution of acidified potassium dichromate. 3) An aqueous solution of acidified potassium dichromate will get warm when it is prepared. It would be best to allow it to cool back to room temp. before beginning the reaction. Once the ketone is formed, it will not react further with acidic dichromate because ketones are difficult to oxidize and dichromate is not a strong enough oxidizer.
Condensed structural formula for cyclohexene?
I'm guessing it would be something close to CH(CH2)5OH HEX...common... hex means 6 so there is 6 carbons in a row C-C-C-C-C-C Its ending is OL making it an alcohol which needs a OH on the end C-C-C-C-C-C-OH cyclo means its all connected. I cant do it on the computer but assume that the begining carbon and the ending carbon for a hexagon with a OH coming off the last Carbon. attach 2 hydrogens to the carbons except for the carbon with an OH. Just attach one on that one. Then your set!
