The melting point of fluorine is -219 Â°C (-363 Â°F). The boiling point of fluorine is -188 Â°C (-307 Â°F).
The same trend normally holds for the melting points of alkane isomers, and indeed that of isopentane is 30 Â°C lower than that of n-pentane. However, the melting point of neopentane, the most heavily branched of the three, is 100 Â°C higher than that of isopentane.
