NEET Chemistry (general) MCQ Question
Which of the following statements about hydrocarbons is correct?
Alkyl halides can be reduced to alkanes using zinc and dilute hydrochloric acid.
Benzene can produce multiple monosubstituted derivatives due to its high degree of unsaturation.
Ethene can be directly converted to propane using hydrogen and a catalyst like Pt.
Methylacetylene is an alkyne that can be reduced to but-2-yne using hydrogen and a catalyst.
Correct Answer
Detailed Explanation
Alkyl halides, except fluorides, can indeed be reduced to alkanes using zinc and dilute hydrochloric acid as shown in the context. Benzene produces only one monosubstituted derivative. Ethene cannot be directly converted to propane; it is an alkene and requires additional steps. Methylacetylene cannot be directly reduced to but-2-yne; it is a different alkyne.
