Similar to 2-mercaptopropan-1-ol, 2,5-dimercaptohexane-3,4-diol reacts with disulfide bridges. However, the equilibrium lies predominantly to the right in this reaction. Explain.

• A. The reaction with 2,5-dimercaptohexane-3,4-diol is intermolecular corresponding to a slower reaction, which makes the equilibrium favor the reactants.
• B. The reaction with 2,5-dimercaptohexane-3,4-diol is intramolecular corresponding to a faster reaction, and the equilibrium favors the reactants.
• C. The reaction with 2,5-dimercaptohexane-3,4-diol is intramolecular corresponding to a faster reaction, and the equilibrium favors the products.
• D. The reaction with 2,5-dimercaptohexane-3,4-diol is intermolecular corresponding to a slower reaction, and the equilibrium favors the reactants.

Answer: (C)
