Abstract
I WISH to direct attention to the fundamental effect of molecular mass on volatility, since it does not support the widely accepted view that volatility decreases with increase in molecular weight. The latter view relies on the various empirical relationships between molecular weight and boiling point, but it has no theoretical basis. Indeed, detailed arguments will be presented elsewhere suggesting that these empirical relationships are fortuitous and that the apparent increase in boiling point with molecular weight is due to other causes. By contrast, the fundamental effect of mass on volatility has a theoretical background and affords a rational explanation of certain boiling-point ‘anomalies’.
