| Abstract: | This paper discusses that the close-eleetricity additional reaction of C 2H 4 and C 2H 2 is difficult or easy,base on the valence-bond theory ,the molecular orbital theory and the difference of stabilization of the middle substance produced by the close-electricity additional reaction.And it discusses the strong and the weak of the acidity between C 2H 4 and C 2H 2,based on the theory of element′s electronagatirity and the difference of stabilization of the ionproduced by their fission. |

| Keywords: | close-electricity additional reaction π bond bond energy β integral unusual fission acidity |
