PEARSON 1 recently pointed out that Pauling's bond energy equation does not give reasonable values of the enthalpy changes for a series of reactions and he has also stressed a number of pitfalls of Pauling's electronegativities. The principle of soft and hard acids and bases (SHAB), on the...
The energy required to break the {eq}C-C {/eq} bond is less than the energy needed to break the {eq}C-H {/eq} bond in the same compound. The following statements are always true for bond enthalpies: If the bond enthalpy is high, then the chemical bond is strong and more energy ...
