Q. In a set of reactions, acetic acid yielded a product D. CH₃COOH —(SOCl₂)→ A —(Benzene, Anhyd. AlCl₃)→ B —(HCN)→ C —(HOH)→ D The structure of D would be :
A) C₆H₅–C(OH)(CH₃)–COOH
B) C₆H₅–CH₂–C(OH)(CH₃)–COOH
C) C₆H₅–CH₂–C(OH)(CH₃)–CN
D) C₆H₅–C(OH)(CH₃)–CN
Explanation
[Solution from source] CH₃COOH → (SOCl₂) CH₃COCl → (C₆H₆, AlCl₃) acetophenone C₆H₅COCH₃ → (HCN) cyanohydrin C₆H₅C(OH)(CH₃)CN → (hydrolysis) C₆H₅C(OH)(CH₃)COOH. The cyanohydrin is only C, and no CH₂ is inserted between ring and carbon. Answer (1).
