  2. Benzamide - Wikipedia

    en.wikipedia.org/wiki/Benzamide

    Benzamide is an organic compound with the chemical formula of C 7 H 7 NO. It is the simplest amide derivative of benzoic acid . In powdered form, it appears as a white solid, while in crystalline form, it appears as colourless crystals. [ 5 ]

  3. Molar mass - Wikipedia

    en.wikipedia.org/wiki/Molar_mass

    Molar mass is closely related to the relative molar mass (M r) of a compound and to the standard atomic weights of its constituent elements. However, it should be distinguished from the molecular mass (which is confusingly also sometimes known as molecular weight), which is the mass of one molecule (of any single isotopic composition), and to ...

    Molar mass: 139.15 g/mol Appearance White solid Density: 1.26 g/cm 3: Melting point: ... Ammonium benzoate can be dehydrated to form benzamide. References

  5. Benzoic acid - Wikipedia

    en.wikipedia.org/wiki/Benzoic_acid

    Benzoic acid (/ b ɛ n ˈ z oʊ. ɪ k /) is a white (or colorless) solid organic compound with the formula C 6 H 5 COOH, whose structure consists of a benzene ring (C 6 H 6) with a carboxyl (−C(=O)OH) substituent.

  6. Benzophenone - Wikipedia

    en.wikipedia.org/wiki/Benzophenone

    In this prototypical example involving benzophenone, the tetrahedral intermediate expels phenyl anion to give benzamide and benzene as the organic products. Benzophenone is a common photosensitizer in photochemistry. It crosses from the S 1 state into the triplet state with nearly 100% yield.

  7. Benzonitrile - Wikipedia

    en.wikipedia.org/wiki/Benzonitrile

    Benzonitrile is a useful solvent and a versatile precursor to many derivatives. It reacts with amines to afford N-substituted benzamides after hydrolysis. [3] It is a precursor to diphenylmethanimine via reaction with phenylmagnesium bromide followed by methanolysis.

  8. Mass fraction (chemistry) - Wikipedia

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

    In chemistry, the mass fraction of a substance within a mixture is the ratio (alternatively denoted ) of the mass of that substance to the total mass of the mixture. [1] Expressed as a formula, the mass fraction is:

  9. Glossary of chemistry terms - Wikipedia

    Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
