| Abstract;The new chemical formula which shows the electronic distrbution of pai-bonded and/or lone pair electrons, could easily distinguishe the chemical property of the molecules. However, Sulfuric acid and Perchloric acid are difficult to show,because the valences become over than the octet theory.Then, the vacant d-orbital should be shown by dotted circle, so as to express the back-donation of lone-pair electrons. The extra-orinary valence of Cl in HClO4 can be easily comprehensible by the back donation into the vacant d-orbital. (author abst.) |
