How molecular size affects properties

How molecular size affects properties

Table of alkanes from methane to decane showing that molar mass and boiling point increase as the number of carbon atoms increases

A hydrocarbon molecule becomes larger as it gains more carbon and hydrogen atoms. As molecular size increases, the boiling point and viscosity increase, while flammability decreases.
