The three isomeric compounds that were formed when 1,2-dibromodecane was treated with potassium hydroxide in aqueous ethanol are to be identified. Concept Introduction: > Vicinal dihalides, upon reaction with a strong base, undergo dehydrohalogenation to produce alkenes having a halogen atom attached to one of the double bonded carbon atoms. > In a dehydrohalogenation reaction, a halogen atom and a hydrogen atom are eliminated from the adjacent carbon atoms. > Reaction of these alkenes with a strong base like sodium amide converts them into alkynes.

β-ocimene is a pleasant smelling hydrocarbon found in the leaves of a certain herbs. It has a molecular formula C10H16 and a UV absorption λmax 232nm. On hydrogenation with a palladium catalyst, 2,6-dimethyloctane is obtained. Ozonolysis β-ocimene followed by the treatment with zinc and acetic acid produces the following fragments:
