Question 21:Identify the major product formed when 2-cyclohexylchloroethane undergoes a dehydrohalogenation reaction. Name the reagent which is used to carry out the reaction.

The correct answer is – The dehydrohalogenation of 2-cyclohexylchloroethane can result in the formation of two different products, depending on the position of the hydrogen atom that is eliminated. However, the major product is most likely to be cyclohexene, which is formed when the beta-hydrogen (adjacent to the carbon bearing the leaving group) is eliminated. The reaction is typically carried out using a strong base, such as potassium hydroxide (KOH), sodium hydroxide (NaOH), or tert-butoxide (t-BuO-), which can remove the acidic hydrogen atom and facilitate the elimination of the leaving group (chloride ion). The reaction conditions may vary depending on the choice of the base, solvent, temperature, and other factors, but the general mechanism involves the formation of a carbanion intermediate that undergoes elimination of the leaving group to form the alkene product.
