A Method To Easily Obtain The Structural Parameters And Its Application

The regularity of changes of organic substance with extensive chain was studied. a method to obtain the structural parameters was suggested according to the name of compounds. that was to say, according to the characteristic of molecular structure, three structural parameters were chosen to describe molecular structure. And correlativity between structural parameters of alkanes, alkenes, aliphatic alcohols, aliphatic aldehydes and alkanones and their physical and chemical properties was studied. The result shows that the number of C atoms has the main influence on the physical and chemical properties, the next is functional group's position and the least is substitution's position,kind and number. The calculation is simple and the parameters have good structural selectivity and correlativity. Therefore, an effective method is provided to forecast some physical and chemical properties.
