WebThe H-C-H bond angle in ethene is ca. 117 degrees and the H-C-C angle is ca. 121.5 degrees. There are two reasons that combine to explain this angular deformation in ethene. First, from these bond angles and Coulson's Theorem ( ref_1, ref_2) we can determine that the C-H sigma bonds are sp A 2.2 hybridized and the C-C sigma bond is sp A 1.7 ... WebDuring the reaction, two moles of H–Cl bonds are formed (bond energy = 432 kJ/mol), releasing 2 × 432 kJ; or 864 kJ. Because the bonds in the products are stronger than those in the reactants, the reaction releases more energy than it consumes:
