7. Which of the following yields an epoxide upon treatment with NaOH? A. cis-2-bromocyclohexanol B. trans-2-bromocyclohexanol...
The treatment of i) trans-2-chlorocyclohexanol with NaOH yields 1,2-epoxycyclohexane, yet the reaction of the ii) cis-2-chlorocyclohexanol isomer under the exact same conditions yields cyclohexanone. Propose reasonable "arrow-pushing" mechanisms, including the intermediate structures for both reactions, and briefly explain for each why the different results are obtained. (Hint: think chair conformation) i) ii) NaOH OH NAOH கயாக H20 H2O my
