naphthalene and camphor are sublimates and also are carbon compounds.is their any relationship between the property of sublimation of a compound and its carbon content? kindly provide me a big list of functional groups .

Expert Answer:

There is no relation between the property of sublimation of a compound and its carbon content. Sublimation refers to the process of transition of a substance from the solid phase to the gas phase without passing through an intermediate liquid phase. It’s an endothermic phase transition that occurs at temperatures and pressures below a substance's triple point in its phase diagram. All solids which possess an appreciable vapour pressure at a certain temperature usually can sublime in air (e.g. ice just below 0°C). For some substances, such as carbon and arsenic, sublimation is much easier than evaporation from the melt, because the pressure of their triple point is very high, and it is difficult to obtain them as liquids. Hence naphthalene and camphor sublimes easily.
