Which of the following statements is/are not correct?
Correct answer: C. Alkanes and alkynes can be distinguished by Br2/CCl4 in Baeyer's test.
- A. Alkanes and alkenes can be distinguished by Br2/CCl4 in halogenation.
- B. Alkanes and alkynes can be distinguished by specific reagents like Tollens' test.
- C. Alkanes and alkynes can be distinguished by Br2/CCl4 in Baeyer's test.
- D. Alkyne-1 and alkyne-2 can be distinguished by specific reagents like Cu2Cl2/NH4OH.
Explanation
The correct answer is Option C, which incorrectly states that alkanes and alkynes can be distinguished by Br2/CCl4 in Baeyer's test. In truth, both alkanes and alkynes do not provide a clear differentiation with these reagents, as they require specific conditions for identification, such as using Tollens' test for alkynes.

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.
