Boiling point trend of alkenes are similar as that of alkenes. Greater the molecular mass , greater will be b.p. however in case of chain isomers like 1-butene and isobutene , increase in surface area or size of molecules causes increase in intermolecular forces hence increases b.p.Thus isobutene will have minimum bp than 1-butene.
