Read e-book online Individuality and Determinism: Chemical and Biological Bases PDF

The importance of human individuality is such that every human capabilities as a different "molecular" unit of the mass of humanity. realizing the traditional foundation for the individuality of the person has lengthy been an goal. the chances were analyzed by means of Julian Huxley, by means of A. E. Needham, by way of Roger Williams, and through others.

4) Free-Valence I n d e x This concept can be considered as the quantum mechanical expression of ideas advanced at the beginning of the century by Flurschein, Werner (residual affinity) and Thiele (partial valency), according to which atoms in a molecule may not have used up their capacity to combine. Each atom has a maximum power or capacity for uniting, and the difference between this maximum value and its real bonding capacity is called the free-valence index. 732-N, (60) When numerical values are determined for q,, p,,, and F , then a molecular diagram is available, a great advance over the classical chemical formula in representing molecular chemical behavior.

In these equations, we have employed the following standard symbols : H,, = J x , H x , d r = a, = ’8, XrXUd“ (28) (30) The integral H,,, called the Coulomb integra1,So depends on the nuclear charge and the type of orbital. Since we supposed the molecule to contain only carbon atoms, ar represents, to a first approximation, the energy of a 2pzelectron of the carbon atom in the presence of the other nuclei; it may be considered to measure approximately the electronegativity of that atom. Its numerical value, referred to the electron removed to infinity, is negative.

FERNhNDEZ-ALONSO [CHAP. 1 is calculated. This method is more general-but more complexthan the first because it provides a unifying explanation, not only of the reactivities of different positionsin amolecule, but also of a whole series of conjugated molecules with respect to the three types of reaction. The dynamic method is divided, in turn, into the “localized method”, due t o m e l a n d , and the “ delocalization theory”. 34 Although it is difficult to establish general criteria for aromatic substitution, the position of maximum reactivity is usually given, according to the static and localization methods, by the following rules : (u) Electrophilic substitution (positive ions) will occur where there is the highest electronic charge, q, the minimum for localization energy, A,( - p ) , and a high value of free valence, F .
