Solution: Compounds A and B are isomers of molecular formula C9H19Br. Both yield the same alkene C as the exclusive product of elimination on being treated with potassium  tert -butoxide in dimethyl sulfoxide.

Compounds A and B are isomers of molecular formula C₉H₁₉Br. Both yield the same alkene C as the exclusive product of elimination on being treated with potassium  tert -butoxide in dimethyl sulfoxide. Hydrogenation of alkene C gives 2,3,3,4-tetramethylpentane. What are the structures of compounds A and B and alkene C?
