**Transcription for an Educational Website** ### Matching Reactions and Compounds Below are three substances labeled I, II, and III, with their corresponding reactions. Match them to their respective stages in the reaction process: - **A:** I - **B:** II - **C:** III ### Reaction Diagram The diagram illustrates a series of chemical reactions involving the transformation of compounds: 1. **Compound I**: - Structure: Phenylacetylene (C₆H₅C≡CH) - Undergoes reaction with Br₂ to form an intermediate. 2. **Compound II**: - Structure: Phenylacetylene derivative (C₆H₅C≡CCH₂) - Reacts with an amine group (NH₂⁻) as indicated by the arrow labeled (a), yielding Compound I. 3. **Compound III**: - Structure: Methylbenzene derivative (C₆H₅CH₂CH₃, with an alkyl group) - Formed by the reaction of Compound II with CH₃Br, followed by hydrogenation with H₂ over a palladium catalyst (Pd) as shown by arrow labeled (b). Each step highlights the critical transformations facilitated by reactions with specific reagents, thereby converting the initial alkyne into a saturated hydrocarbon.
