Which of the following test can be used for distinguishing an alkane and an alkene:
Correct answer: B. Baeyer's test (cold, dilute, alkaline KMNO4)
- A. Bromine water test
- B. Baeyer's test (cold, dilute, alkaline KMNO4)
- C. Ozonolysis
- D. Both A and B
Explanation
The correct answer is Baeyer's test, as it specifically targets the unique reactivity of alkenes through oxidation, which alkanes do not undergo under the same conditions. The bromine water test, while useful for indicating unsaturation, is not definitive in distinguishing the two classes of hydrocarbons. Ozonolysis is a reaction that does not serve as a simple test for this distinction. Therefore, Baeyer's test is the most appropriate choice for distinguishing between an alkane and an alkene.

About Chemistry of Hydrocarbons
Hydrocarbons are studied through the structures and reactions of alkanes, alkenes, alkynes and aromatic compounds. Coverage includes free radical substitution in alkanes, electrophilic addition to carbon-carbon multiple bonds, benzene substitution, aromatic stability and the difference between addition reactions of alkenes and substitution reactions of benzene.
