WebThe delta G of a covalent bond is around -50 to -100 kcal/mol (-210 to -420 kJ/mol), i.e. a considerable amount of energy is stored in it. This does not necessarily mean that the respective molecules are in a state of high energy. They may even be said to be in a state of low energy since the energy is used to maintain the bonds. WebSo we can conveniently say that a molecule of methane has a total of four non-polar covalent bonds. Single and Multiple Covalent Bonds.
