It is also easily biodegradable in soil. Polar covalent bonds behave as if the bonded atoms have localized fractional charges that are equal but opposite (i.e., the two bonded atoms generate a dipole). This difference in fusions causes the phenanthrene to have five resonance structures which is one more than anthracene. There are two fairly distinct problems involved in a treatment of the stability of the benzene ring. In simple words, Anthracene can be purified using the process of sublimation or desublimation.
