Websulfuric acid led to alkene products in less than 20% yield, whereas use of hydrochloric acid gave a mixture of cyclohexene and methylcyclopentenes (14% of the product mixture) due to isomerisation.22 The choice of acid is clearly important. Sulfuric acid is one of the most common ways to dehydrate alcohols in a lab, however, it is also a strong WebIn this experiment, cyclohexanol is dehydrated by aqueous sulfuric acid to produce cyclohexene as the sole product [equation (1)], and no rearrangement is possible in this reaction.

WebSulfuric Acid Test Add 2 drops of your cyclohexene to 10 drops of concentrated sulfuric acid in a test tube. Shake the tube well but carefully, and note the result. For comparison, repeat the test using the saturated alkane. Waste Disposal Pour the tube contents into a beaker containing at least 20 mL of water. Discard this solution into the waste WebThe combustion of cyclohexene produces a sootier flame than the cyclohexane. This is because the carbon to hydrogen ratio is higher in cyclohexene. When the percentage of carbon is higher, more oxygen is needed to oxidize the compound. Hence, in incomplete combustion, due to insufficient amount of oxygen provided, more black soot will be … WebIn this experiment, cyclohexanol is dehydrated by aqueous sulfuric acid to produce cyclohexene as the sole product [equation (1)], and no rearrangement is possible in this reaction.
