The molar mass of atoms of an element is given by the relative atomic mass of the element multiplied by the molar mass constant, M u ≈ 1.000 000 × 10 −3 kg/mol ≈ 1 g/mol. For normal samples from Earth with typical isotope composition, the atomic weight can be approximated by the standard atomic weight [ 2 ] or the conventional atomic weight.
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.
A mass spectrum is a histogram plot of intensity vs. mass-to-charge ratio (m/z) in a chemical sample, [1] usually acquired using an instrument called a mass spectrometer. Not all mass spectra of a given substance are the same; for example, some mass spectrometers break the analyte molecules into fragments ; others observe the intact molecular ...
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.
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.
Benzimidazole is a base: . C 6 H 4 N(NH)CH + H + → [C 6 H 4 (NH) 2 CH] +. It can also be deprotonated with stronger bases: . C 6 H 4 N(NH)CH + LiH → Li [C 6 H 4 N 2 CH] + H 2. The imine can be alkylated and also serves as a ligand in coordination chemistry.
