# Which are stronger bonds, ionic bonds or intermolecular forces? Which have higher melting points, ionic compounds or molecular compounds?

Jan 21, 2017

Molecularity is a very important concept to apply in this context. Carbon as diamond and graphite is non-molecular, with no molecular boundaries, and thus unfeasibly high melting and boiling points. On the other hand methane, whose $C - H$ bonds are certainly stronger than $C - C$ bonds, is a room temperature gas, precisely because this is a molecular material consisting of discrete molecules of $C {H}_{4}$, which are bound together by weak dispersion forces.
