  2. Hydrogen peroxide - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_peroxide

    Hydrogen peroxide is a chemical compound with the formula H 2 O 2.In its pure form, it is a very pale blue [5] liquid that is slightly more viscous than water.It is used as an oxidizer, bleaching agent, and antiseptic, usually as a dilute solution (3%–6% by weight) in water for consumer use and in higher concentrations for industrial use.

  3. Chemical nomenclature - Wikipedia

    en.wikipedia.org/wiki/Chemical_nomenclature

    The IUPAC's rules for naming organic and inorganic compounds are contained in two publications, known as the Blue Book [1] [2] and the Red Book, [3] respectively. A third publication, known as the Green Book , [ 4 ] recommends the use of symbols for physical quantities (in association with the IUPAP ), while a fourth, the Gold Book , [ 5 ...

  4. Regioselectivity - Wikipedia

    en.wikipedia.org/wiki/Regioselectivity

    In organic chemistry, regioselectivity is the preference of chemical bonding or breaking in one direction over all other possible directions. [1] [2] It can often apply to which of many possible positions a reagent will affect, such as which proton a strong base will abstract from an organic molecule, or where on a substituted benzene ring a further substituent will be added.

  5. Structural isomer - Wikipedia

    en.wikipedia.org/wiki/Structural_isomer

    In chemistry, a structural isomer (or constitutional isomer in the IUPAC nomenclature [1]) of a compound is another compound whose molecule has the same number of atoms of each element, but with logically distinct bonds between them. [2] [3] The term metamer was formerly used for the same concept. [4]

  6. Isomer - Wikipedia

    en.wikipedia.org/wiki/Isomer

    Both have a chain of three carbon atoms connected by single bonds, with the remaining carbon valences being filled by seven hydrogen atoms and by a hydroxyl group comprising the oxygen atom bound to a hydrogen atom. These two isomers differ on which carbon the hydroxyl is bound to: either to an extremity of the carbon chain propan-1-ol (1 ...

  7. Hydroperoxide - Wikipedia

    en.wikipedia.org/wiki/Hydroperoxide

    Many industrial peroxides are produced using hydrogen peroxide. Reactions with aldehydes and ketones yield a series of compounds depending on conditions. Specific reactions include addition of hydrogen peroxide across the C=O double bond: R 2 C=O + H 2 O 2 → R 2 C(OH)OOH. In some cases, these hydroperoxides convert to give cyclic diperoxides:

  8. Isotopomer - Wikipedia

    en.wikipedia.org/wiki/Isotopomer

    The result is that the molecules are either constitutional isomers or stereoisomers solely based on isotopic location. The term isotopomer was first proposed by Seeman and Paine in 1992 to distinguish isotopic isomers from isotopologues (isotopic homologues). [1] [2]

  9. Hydroperoxyl - Wikipedia

    en.wikipedia.org/wiki/Hydroperoxyl

    Together with its conjugate base superoxide, hydroperoxyl is an important reactive oxygen species.Unlike • O − 2, which has reducing properties, HO • 2 can act as an oxidant in a number of biologically important reactions, such as the abstraction of hydrogen atoms from tocopherol and polyunstaturated fatty acids in the lipid bilayer.
