  2. List of carboxylic acids - Wikipedia

    en.wikipedia.org/wiki/List_of_carboxylic_acids

    The systematic IUPAC name is not always the preferred IUPAC name, for example, lactic acid is a common, and also the preferred, name for what systematic rules call 2-hydroxypropanoic acid. This list is ordered by the number of carbon atoms in a carboxylic acid.

  3. Pentane - Wikipedia

    en.wikipedia.org/wiki/Pentane

    Pentane is an organic compound with the formula C 5 H 12 —that is, an alkane with five carbon atoms. The term may refer to any of three structural isomers, or to a mixture of them: in the IUPAC nomenclature, however, pentane means exclusively the n-pentane isomer, in which case pentanes refers to a mixture of them; the other two are called isopentane (methylbutane) and neopentane ...

    This would still exclude urea. Moreover, this definition still leads to somewhat arbitrary divisions in sets of carbon-halogen compounds. For example, CF 4 and CCl 4 would be considered by this rule to be "inorganic", whereas CHF 3, CHCl 3, and C 2 Cl 6 would be organic, though these compounds share many physical and chemical properties ...

  5. IUPAC nomenclature of organic chemistry - Wikipedia

    en.wikipedia.org/wiki/IUPAC_nomenclature_of...

    The longest possible main alkane chain is used; therefore 3-ethyl-4-methylhexane instead of 2,3-diethylpentane, even though these describe equivalent structures. The di-, tri- etc. prefixes are ignored for the purpose of alphabetical ordering of side chains (e.g. 3-ethyl-2,4-dimethylpentane, not 2,4-dimethyl-3-ethylpentane).

    Even silicon–silicon pi bonds are possible. However, these bonds are less stable than the carbon analogues. Disilane and longer silanes are quite reactive compared to alkanes. Disilene and disilynes are quite rare, unlike alkenes and alkynes. Examples of disilynes, long thought to be too unstable to be isolated [10] were reported in 2004. [11]

  7. 2-Methylpentane - Wikipedia

    en.wikipedia.org/wiki/2-Methylpentane

    2-Methylpentane, trivially known as isohexane, is a branched-chain alkane with the molecular formula C 6 H 14. It is a structural isomer of hexane composed of a methyl group bonded to the second carbon atom in a pentane chain.

    An example of a common reaction is a substitution reaction written as: Nu − + C−X → C−Nu + X −. where X is some functional group and Nu is a nucleophile. The number of possible organic reactions is infinite. However, certain general patterns are observed that can be used to describe many common or useful reactions.

  9. Alkyl group - Wikipedia

    en.wikipedia.org/wiki/Alkyl_group

    In organic chemistry, an alkyl group is an alkane missing one hydrogen. [1] The term alkyl is intentionally unspecific to include many possible substitutions. An acyclic alkyl has the general formula of −C n H 2n+1. A cycloalkyl group is derived from a cycloalkane by removal of a hydrogen atom from a ring and has the general formula −C n H ...
