  2. Benzoic acid - Wikipedia

    en.wikipedia.org/wiki/Benzoic_acid

    Benzoic acid is cheap and readily available, so the laboratory synthesis of benzoic acid is mainly practiced for its pedagogical value. It is a common undergraduate preparation. Benzoic acid can be purified by recrystallization from water because of its high solubility in hot water and poor solubility in cold water. The avoidance of organic ...

  4. Azeotrope tables - Wikipedia

    en.wikipedia.org/wiki/Azeotrope_tables

    This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.

  5. Ortho effect - Wikipedia

    en.wikipedia.org/wiki/Ortho_effect

    Ortho effect is an organic chemistry phenomenon where the presence of a chemical group at the at ortho position or the 1 and 2 position of a phenyl ring, relative to the carboxylic compound changes the chemical properties of the compound.

  6. Neutralization (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Neutralization_(chemistry)

    A weak acid cannot always be neutralized by a weak base, and vice versa. However, for the neutralization of benzoic acid (K a,A = 6.5 × 10 −5) with ammonia (K a,B = 5.6 × 10 −10 for ammonium), K = 1.2 × 10 5 >> 1, and more than 99% of the benzoic acid is converted to benzoate.

  7. Acid dissociation constant - Wikipedia

    en.wikipedia.org/wiki/Acid_dissociation_constant

    In chemistry, an acid dissociation constant (also known as acidity constant, or acid-ionization constant; denoted ⁠ ⁠) is a quantitative measure of the strength of an acid in solution. It is the equilibrium constant for a chemical reaction

  9. Aniline - Wikipedia

    en.wikipedia.org/wiki/Aniline

    Aniline and its ring-substituted derivatives react with nitrous acid to form diazonium salts. One example is benzenediazonium tetrafluoroborate . Through these intermediates, the amine group can be converted to a hydroxyl ( −OH ), cyanide ( −CN ), or halide group ( −X , where X is a halogen ) via Sandmeyer reactions .
