Methyl alcohol, atom polarization

In an electrostatic potential map, the color red indicates regions of a molecule that are electron-rich. The map shows that chlorine is the most electronegative atom in methyl alcohol, and the direction of polarity of the C-Cl bond is ... 

Hexane is a solvent with only hydrogen and carbon atoms and has a 100% nonpolar character, 8, = 14.9. Acetone is a solvent with carbon, hydrogen, and polar carbonyl group. It has a nonpolar 6j = 15.5, a polar 5p = 10.4, and 5 = 7.0. Methyl alcohol is a solvent with nonpolar 6 = 15.1, a polar 8p = 12.3, and S, = 22.3. The percentage of each delta value of the total solubility parameter of the three solvents are ... 

Oxygenation of 2-substituted adamantanes with methyl(trifluoromethyl)dioxirane showed a reaction constant, p = -2.31, consistent with a strongly electron-demanding transition state. Analysis of the effect of solvents on the rate yielded a positive regression coefficient with Dimroth-Reichardt Ej solvent polarity parameter. A mechanism involving an electrophilic O atom insertion has been postulated for the formation of alcohols and carbonyl compounds.201... 

The ff constants for the 4,6-dimethyl-s-triazinyl group were evaluated by two independent methods (1) from the pK values of m- and p-(4,6-dimethyl-2-triazinyl)benzoic acids (series 10) and (2) from the spectra of 4,6-dimethyl-2-(m-/p-fluorophenyl)triazines (series 9) in various solvents (74JOC2591). That the ff] values in alcoholic media and in DMSO are very close can be accounted for by the low protophilicity of heterocyclic nitrogen atoms of the triazine ring and by their small steric accessibility in the presence of two methyl groups in the ring. At the same time, the polarity of the medium exerts an appreciable effect on the value of the inductive constants (see Table XIII).
