1-Hexene was treated with dilute sulfuric acid. The product of that reaction was reacted with potassium dichromate in sulfuric acid. This product was then treated with methanol in hydrochloric acid. What is the major product of this series of reactions?

Question

Quizplus · Accepted Answer

The first reaction with dilute sulfuric acid will convert 1-hexene to 1-hexanol. The second reaction with potassium dichromate in sulfuric acid will oxidize the alcohol to the corresponding aldehyde, which in this case is hexanal. The third reaction with methanol in hydrochloric acid will convert hexanal to its corresponding acetal, which is 2,2-dimethyl-5-bromohexanal. Therefore, the major product is option II.
