Fumes are generally obtained by the condensation of vapours during sublimation, distillation, boiling and several other chemical reactions.Ethanol is a liquid at room temperature (refer to Table 1 for the melting and boiling points of ethanol).For any pure liquid at atmospheric pressure ( 013 bar) the temperature at which the liquid and vapours are at equilibrium is called boiling point of the liquid.The boiling point of water is 100°C at 013 bar pressure.conductors of electricity as we have seen in Chapter From the data on the boiling and melting points of the above compounds, we can conclude that the forces of attraction between these molecules are not very strong.If the above experiment is repeated with methyl alcohol, acetone and ether, it is observed that different liquids have different equilibrium vapour pressures at the same temperature, and the liquid which has a higher vapour pressure is more volatile and has a lower boiling point.Boiling point of a liquid depends on the altitude of the place; at high altitude the boiling point decreases.There are numerous physical properties of elements such as melting and boiling points, heats of fusion and vaporization, energy of atomization, etc.They show a regular increase in boiling point with increase in size i.e., every – CH2 group added increases boiling point by 20–30 K.Lothar Meyer plotted the physical properties such as atomic volume, melting point and boiling point against atomic weight and obtained a periodically repeated pattern.It is observed (Table 1 2) that pentane having a continuous chain of five carbon atoms has the highest boiling point (30 1K) whereas 2,2 – dimethylpropane boils at 28 5K.At constant temperature of its boiling point Tb and at constant pressure.Non-metals are usually solids or gases at room temperature with low melting and boiling points (boron and carbon are exceptions).Structures I and possess same molecular formula but differ in their boiling points and other properties.Like alkanes, straight chain alkenes have higher boiling point than isomeric branched chain compounds.
