    CH 3 CH 2 OH . Parentheses are used to indicate multiple identical groups, indicating attachment to the nearest non-hydrogen atom on the left when appearing within a formula, or to the atom on the right when appearing at the start of a formula: (CH 3) 2 CHOH or CH(CH 3) 2 OH . In all cases, all atoms are shown, including hydrogen atoms.

    However, the empirical formula for hexane is C 3 H 7. Likewise the empirical formula for hydrogen peroxide, H 2 O 2, is simply HO, expressing the 1:1 ratio of component elements. Formaldehyde and acetic acid have the same empirical formula, CH 2 O. This is also the molecular formula for formaldehyde, but acetic acid has double the number of atoms.

  4. Orthoformic acid - Wikipedia

    en.wikipedia.org/wiki/Orthoformic_acid

    Orthoformic acid or methanetriol is a chemical compound with the formula H C(OH) 3. In this molecule, the central carbon atom is bound to one hydrogen and three hydroxyl groups. Orthoformic acid was long held to be a hypothetical chemical compound , as it was expected to decompose instantly into formic acid and water, making it too unstable to ...

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

    A fraction in chemistry is a quantity collected from a batch of a substance in a fractionating separation process. In such a process, a mixture is separated into fractions, which have compositions that vary according to a gradient. A fraction can be defined as a group of chemicals that have similar boiling points.
