The atoms in the molecules of organic compounds are held together by attraction forces, which are generally known as covalent bonds. The attraction is due to a resonance phenomenon between the outer electrons of the atoms which occurs at a distance of the order of magnictude of 1Å and can be regarded as a continuous exchange of electrons (shared electron pair). This resonance has a corresponding sharply defined energy minimum with a maximum energy difference(potential well) of approximately 100kcal for the hydroden molecule, which one has to supply in order to split one molecule of hydrogen into two hydrogen atoms.
