Question

Quizplus · Accepted Answer

The major organic product of the given sequence of reactions is compound 2. The starting material, 2-butanol, undergoes oxidation with acidic potassium dichromate (K2Cr2O7) to form 2-butanone (also known as methyl ethyl ketone) as the intermediate product. Further treatment of 2-butanone with NaBH4 reduces it to the final product, 2-butanol. Hence, there is no net reaction overall, and the original compound is regenerated. However, during the course of the reaction, 2-butanone is the major organic product formed.
