MolSynapse / Question bank / Reduction, Oxidation and Hydrolysis in Organic Chemistry / Baeyer-Villiger and epoxidation

JEE Main levelSingle correct optionDifficulty 2 of 3ro103

Cyclohexanone is treated with $CF X_{3} CO X_{3} H$ , and the product is then heated with aqueous $NaOH$ followed by acidification with $H X_{3} O X^{+}$ . The final product is

Ahexane-1,6-diol
B6-hydroxyhexanoic acid
Ccyclohexane-1,2-diol
Dhexanedioic acid

Answer: B

Baeyer-Villiger oxidation gives the lactone oxepan-2-one. Hot aqueous

NaOH

opens the lactone by ester hydrolysis to the sodium salt of 6-hydroxyhexanoic acid. Acidification gives

HO - (CH X_{2}) X_{5} - COOH

.
