In a redox reaction, where does the electron-acceptor molecule transfer electrons?

• A. To the catalyst
• B. To the oxidizing agent
• C. To the solvent
• D. To the reducing agent

Answer: (D)

Verified step by step guidance

1. Understand the concept of a redox reaction: A redox (reduction-oxidation) reaction involves the transfer of electrons between two species. It consists of two half-reactions: oxidation (loss of electrons) and reduction (gain of electrons).
2. Identify the roles of the agents: In a redox reaction, the oxidizing agent is the species that gains electrons and is reduced, while the reducing agent is the species that loses electrons and is oxidized.
3. Determine the electron flow: Electrons are transferred from the reducing agent to the oxidizing agent. The reducing agent donates electrons, and the oxidizing agent accepts them.
4. Clarify the role of the electron-acceptor: The electron-acceptor in a redox reaction is the oxidizing agent, as it accepts electrons from the reducing agent.
5. Conclude the electron transfer: Therefore, the electron-acceptor molecule transfers electrons to the reducing agent, completing the redox process.
