Acid Basics
... Acids are rated on their strength, or ability to give up protons, on the pH scale. pH stands for power of hydrogen and works like this: the pH scale goes from 1 (strongest acid) to 14 (weakest acid) with 7 being neutral. Water is exactly 7. By the way, strong acids are weak bases and vice versa. Fin ...

Acidic and Basic Character of Carboxylic Acids
... Electron-withdrawing substituents increase the acidity of carboxylic acids. The inductive effect of electron-withdrawing groups close to the carboxy group causes an increase in acidity. Three electron-withdrawing groups on the -carbon sometimes results in acidity near that of some inorganic acids. ...

Nucleophilic acyl substitution
Nucleophilic acyl substitution describe a class of substitution reactions involving nucleophiles and acyl compounds. In this type of reaction, a nucleophile – such as an alcohol, amine, or enolate – displaces the leaving group of an acyl derivative – such as an acid halide, anhydride, or ester. The resulting product is a carbonyl-containing compound in which the nucleophile has taken the place of the leaving group present in the original acyl derivative. Because acyl derivatives react with a wide variety of nucleophiles, and because the product can depend on the particular type of acyl derivative and nucleophile involved, nucleophilic acyl substitution reactions can be used to synthesize a variety of different products.
