Resonance forms forms must obey normal rules of valency. The resonance resonance hybrid is more stable than any individual resonance form. A useful technique for drawing resonance forms Section 2. Any three-atom three-atom grouping with a multiple bond adjacent to a nonbonding p nonbonding p orbital has two resonance forms. One atom in in the grouping has a lone electron pair, a vacant orbital orbital or a single electron.
By recognizing these three-atom pieces, resonance forms can be generated. Acids and bases Sections 2. Water can act either as an acid or as a base. Acid and base strength strength Section 2. A strong strong acid reacts almost completely with water Section 2.
The strength strength of an acid in water is indicated by K by K a, the acidity constant. Strong acids have large acidity constants, and weaker acids have smaller acidity acidity constants. The p K a is normally used to express acid strength. A strong acid has a small p K a, and a weak acid has a large p K a. The conjugate base of a strong acid is a weak base, and the conjugate base of a weak acid is a strong base.
Predicting acid — base reactions from p K a Section 2. An acid with a low p K a stronger acid reacts with the conjugate base of an acid with a high p K a stronger base. In other words, the products of an acid — base reaction are more stable than the reactants. Organic acids and organic bases Section 2. There are two main types types of organic acids: i. Acids that contain hydrogen bonded to oxygen. The main type of organic base contains a nitrogen atom with a lone electron pair.
Lewis acids and bases Section 2. A Lewis acid accepts an electron electron pair. A Lewis acid may have either a vacant low-energy orbital or a polar bond to hydrogen.
Examples include metal cations, halogen acids, group 3 compounds and transition-metal compounds. A Lewis Lewis base has a pair of nonbonding electrons. Most oxygen- and nitrogen-containing organic organic compounds are Lewis Lewis bases. Many organic Lewis bases have more than one basic site. A curved arrow shows the movement movement of electrons from from a Lewis base to a Lewis Lewis acid.
Noncovalent interactions in molecules Section 2. Dipole — dipole dipole interactions occur between polar molecules as a result of electrostatic interactions among dipoles. These interactions may be either attractive or repulsive. The attractive geometry is lower in energy and predominates. Dispersion forces forces result from from the constantly changing electron distribution within molecules.
These forces are transient and weak, but their cumulative effect may be important. Hydrogen bonds. Hydrogen bonds form between a hydrogen bonded to an electronegative atom and an unshared electron pair on another electronegative atom. Hydrogen bonds are extremely important in living living organisms. Hydrophilic substances dissolve in water because they are capable of forming forming hydrogen bonds. The larger the number, the more electronegative the element.
More electronegative a H 2. The partial negative charge is placed on the more electronegative atom, and the partial positive charge is placed on the less electronegative atom. This edition by Pearson, however, had many pages blank or partially printed because of which I had to return the book.
In summary — I recommend the author but Pearson did not have good quality control or maybe I just got unlucky with my copy. Fay in pdf from following download links.
