Study on the relationship between normal boiling points of alkanes and their molecular structures by using molecular topology;

From the relation between vaporization heat(or normal boiling point) and carbon number,the correlation between vaporization heat and normal boiling point was theoretically deduced,and a simple but valid equation was fitted:Hυ=23.
