Q: What is the correct answer for CUET UG Chemistry Q35?

The correct answer is a. (A) Phenol → Benzene: Phenol can be reduced to benzene by distillation with zinc dust (Zn) (III).(B) CH₃CH₂OH → C₂H₅OC₂H₅: Ethanol undergoes intermolecular dehydration in the presence of H₂SO₄ at 413 K to form diethyl ether (IV).(C) Cyclohexanone → Cyclohexanol: Cyclohexanone (a ketone) is reduced to cyclohexanol (a secondary alcohol). This typically requires a reducing agent like NaBH₄ or H₂/Ni.

FirstInTest · Accepted Answer

(A) Phenol → Benzene: Phenol can be reduced to benzene by distillation with zinc dust (Zn) (III).(B) CH₃CH₂OH → C₂H₅OC₂H₅: Ethanol undergoes intermolecular dehydration in the presence of H₂SO₄ at 413 K to form diethyl ether (IV).(C) Cyclohexanone → Cyclohexanol: Cyclohexanone (a ketone) is reduced to cyclohexanol (a secondary alcohol). This typically requires a reducing agent like NaBH₄ or H₂/Ni. However, according to the provided solution, it maps to (I) Na₂Cr₂O₇ in presence of H₂SO₄. (Note: Na₂Cr₂O₇/H₂SO₄ is a strong oxidizing agent and would not convert a ketone to an alcohol. This indicates an inconsistency in the question/solution).(D) CH₃CH₂OH → CH₂=CH₂: Ethanol undergoes intramolecular dehydration in the presence of H₂SO₄ at 443 K to form ethene (II).Thus, the mapping is (A)-(III), (B)-(IV), (C)-(I), (D)-(II).
