Answer» Correct Answer - D Boiling point increases with increase in size of hydrocarbon part for the same haloalkanes All the given haloalkenes contain same halogen atom i.e., bromine but the number of carbon atoms in hydrocarbon part of the molecule are increasing from ethane to benzene. So, the boiling point is minimum for 1-bromoethane and maximum for 1-bromobenzene.
