Reaction energy diagram organic chemistry

energy diagram (or reaction energy diagram): a graph of the energy of a reaction against the progress of the reaction. enthalpy: a thermodynamic state function, generally measured in kilojoules per mole. In chemical reactions the enthalpy change (deltaH) is related to changes in the free energy (deltaG) and entropy (deltaS) by the equation: 1.2.3 Guidelines about Formal Charges in Lewis Structures. The purpose of formal charges is to compare the difference between the number of valence electrons in the free atom and the number of electrons the atom "owns" when it is bonded.The smaller the difference the "happier" (more stable) the atom is.
