We report the results of a calculation of the normal boiling points of a representative set of 200 organic molecules through the application of QSPR theory. For this purpose we have used a particular set of flexible molecular descriptors, the so called C
The boiling points of organic compounds can give important clues to other physical properties and structural characteristics. A liquid boils when its vapor pressure is equal to the atmospheric pressure. Vapor pressure is determined by the kinetic energy of molecules. Kinetic energy is related to tempe...
Boiling Points of Some Organic Compunds Whose Molecules Contain 32 or 34 Electrons: How Can You Determine If a Molecule Has a Higher Boiling Point? Melting and Boiling Points, Densities and Solubility for Inorganic Compounds in Water: How Can You Determine If a Molecule Has a Higher Boiling Po...
text>We recently reported a successful correlation of the normal boiling points of 298 organic compounds containing O, N, Cl, and Br with two molecular descriptors.' In the present study the applicability of these two descriptors for the prediction of boiling points for various other classes of ...
Answer to: The boiling point of a pure liquid ___ as external pressure decreases. A. increases B. decreases C. is constant D. not enough...
Based on the characteristics of molecular structure, the adjacent matrix and dyeing matrix were used to characterize the molecular structure of alkane and cycloalkane, a new method——the group contribu-tion method, was developed to calculate the boiling points of alkane and cycloalkanes from molecul...
