AIIMS 2018 Chemistry Reactions of Alcohols MCQ Question

Heating octahydrobenzofuran with HBr leads to the formation of a bromoalkane through electrophilic addition, where the bromine atom adds to the more substituted carbon of the double bond. This product then reacts with concentrated sulfuric acid, facilitating a dehydration reaction that results in the formation of 1-bromo-2-vinylcyclohexane, which features a vinyl group adjacent to the bromine. Other options may represent different structural isomers or products that do not arise from the specified reactions, demonstrating the importance of understanding reaction mechanisms and regioselectivity in organic chemistry.
