Aromatic compounds are more stable than alkanes because of resonance. Due to resonance, the pi-electron charge in these compounds gets delocalised. This delocalisation of electrons results in the stronger bonds than the normal pi- bonds and sigma bonds. 
Because aromatic compounds (like benzene) are flat, they stack well, and so have higher melting and boiling points than corresponding alkanes and alkenes.
