Why do free-radical reactions involving neutral reactants and intermediates respond to substituent changes that modify electron distribution One explanation has been based on the idea that there would be some polar character in the transition state because of the electronegativity differences of the reacting atoms ... 

Turning now to electrophilic aromatic substitution in (trifluoromethyl)benzene, we consider the electronic properties of a trilluorornethyl group. Because of their high electronegativity the three fluorine atoms polarize the electron distribution in their- a bonds to car bon, so that car bon bear s a partial positive charge. 

Most organic compounds are electrically neutral they have no net charge, either positive or negative. We saw in Section 2.1, however, that certain bonds within a molecule, particularly the bonds in functional groups, are polar. Bond polarity is a consequence of an unsymmetrical electron distribution in a bond and is due to the difference in electronegativity of the bonded atoms.

Nitrogen is more electronegative than carbon, and this influences the electron distribution in the Jt-electron system in pyridine through inductive effects, such that nitrogen is electron rich. In addition, the... 

Two atoms of the same electronegativity will share electrons equally in a pure covalent bond therefore, any molecule that contains atoms of only one element, like H2 or CI2, has pure covalent bonding. Two atoms of different electronegativities, however, will have either the distorted electron distribution of a polar bond or the complete electron transfer of an ionic bond. Table 5-6 interprets the bonding between two elements as a function of the difference in their electronegativity. 

Hydrophobic parameters include charge distribution, electron density, electronegativity, dipole moment, and hydrogen bond.
