What reaction type involves the transfer of electrons between reactants?

• A. Synthesis reaction
• B. Redox reaction
• C. Decomposition reaction
• D. Combination reaction

Answer: (B)

The correct response focuses on redox reactions, which are characterized by the transfer of electrons between reactants. In a redox reaction, one species undergoes oxidation, which involves losing electrons, while another species undergoes reduction, meaning it gains electrons. This electron transfer is fundamental to many biological and chemical processes, including cellular respiration and photosynthesis. Synthesis reactions typically involve combining simple reactants to form a more complex product, while decomposition reactions involve breaking down a compound into simpler substances. Combination reactions are often synonymous with synthesis reactions, as they both involve combining substances. None of these types of reactions inherently describe the transfer of electrons between reactants, which is a defining feature of redox reactions.
