When hexan-3-ol is treated with concentrated HBr solution, the reaction proceeds with partial racemization with excess inversion. Provide the possible mechanism accounting for racemization resulting in greater inversion than retention of configuration.

• A. Two possible mechanisms:(1) 50% inversion and 50% retention of configuration(2) 100% inversion of configuration
• B. Two possible mechanisms:(1) 50% inversion and 50% retention of configuration(2) 100% inversion of configuration
• C. Two possible mechanisms:(1) 50% inversion and 50% retention of configuration(2) 100% inversion of configuration
• D. Two possible mechanisms:(1) 50% inversion and 50% retention of configuration(2) 100% inversion of configuration

Answer: (A)
