Compound that is expected to have highest boiling point has to be identified. Concept Introduction: The dipole moment is produced by two equal but opposite charges separated by a distance. The one with molecular dipole moment will exhibit high boiling point. Hydrogen bonding is a special type of dipole-dipole interaction in a polar bond which has hydrogen atom and a highly electronegative atom such as Nitrogen, Oxygen and Fluorine. The compounds that possess hydrogen bonding will exhibit high boiling point. In hydrocarbons, the boiling point appears to increase with increase in molecular weight. Branched hydrocarbon causes decrease in boiling point due to a smaller surface area.
