  2. Newman projection - Wikipedia

    en.wikipedia.org/wiki/Newman_projection

    3D structure A Newman projection is a drawing that helps visualize the 3-dimensional structure of a molecule. [ 1 ] This projection most commonly sights down a carbon-carbon bond, making it a very useful way to visualize the stereochemistry of alkanes.

  3. Alkyl group - Wikipedia

    en.wikipedia.org/wiki/Alkyl_group

    Thus, the name is 3-methylpentane to avoid ambiguity: The 3- is because the methyl is attached to the third of the five carbon atoms. If there is more than one of the same alkyl group attached to a chain, then the prefixes are used on the alkyl groups to indicate multiples (i.e., di, tri, tetra, etc.)

  4. Alkane - Wikipedia

    en.wikipedia.org/wiki/Alkane

    Alkanes with more than three carbon atoms can be arranged in various ways, forming structural isomers.The simplest isomer of an alkane is the one in which the carbon atoms are arranged in a single chain with no branches.

  6. 3-Methylpentane - Wikipedia

    en.wikipedia.org/wiki/3-Methylpentane

    It is of similar structure to the isomeric 2-methylpentane, which has the methyl group located on the second carbon of the pentane chain. As of early 1990s, it was present in American [3] and European [4] gasoline in small amounts, and by 2011 its share in US gas varied between 1.5 and 6% [5] It has close research and motor octane numbers of 74 ...

    en.wikipedia.org/wiki/2-Methylpentane

    As of early 1990s, it was present in American [4] and European [5] gasoline in small amounts, and by 2011 its share in US gas varied between 2 and 8%. [6] Using a quantitative structure-activity relationship (QSAR) prediction model, 2-Methylpentane has a research octane number (RON) of 75, motor octane number (MON) of 77, and cetane number (CN ...

  9. 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).
