Answer
Predicted Products of Benzyl Alcohol Reactions
Reaction 1: Benzyl Alcohol with TsCl, Pyridine and NaBr in DMSO
Step 1: The hydroxyl group in benzyl alcohol (C₆H₅CH₂OH) reacts with tosyl chloride (TsCl) in the presence of pyridine, forming benzyl tosylate (C₆H₅CH₂OTs).
Step 2: In a polar aprotic solvent like DMSO, NaBr introduces a nucleophile (Br⁻) which substitutes the tosylate group via an SN2 reaction.
The final product formed is benzyl bromide (C₆H₅CH₂Br).
Correct Answer: Option D – Benzyl Bromide
Reaction 2: Benzyl Alcohol with Sodium (Na)
Step: When benzyl alcohol reacts with metallic sodium (Na), it undergoes deprotonation forming benzyl sodium alkoxide (C₆H₅CH₂O⁻ Na⁺) and liberates hydrogen gas (H₂).
This is a typical acid-base reaction and no substitution or oxidation occurs.
Correct Answer: Option B – Benzyl Sodium Alkoxide
Final Answers Summary
- Question 1: Option D – Benzyl Bromide
- Question 2: Option B – Benzyl Sodium Alkoxide
