  4. Alkane - Wikipedia

    en.wikipedia.org/wiki/Alkane

    For example, cyclobutane and methylcyclopropane are isomers of each other (C 4 H 8), but are not isomers of butane (C 4 H 10). Branched alkanes are more thermodynamically stable than their linear (or less branched) isomers. For example, the highly branched 2,2,3,3-tetramethylbutane is about 1.9 kcal/mol more stable than its linear isomer, n ...

  5. Hydrocarbon - Wikipedia

    en.wikipedia.org/wiki/Hydrocarbon

    In organic chemistry, a hydrocarbon is an organic compound consisting entirely of hydrogen and carbon. [ 1 ] : 620 Hydrocarbons are examples of group 14 hydrides . Hydrocarbons are generally colourless and hydrophobic ; their odor is usually faint, and may be similar to that of gasoline or lighter fluid .

  6. 1-Hexyne - Wikipedia

    en.wikipedia.org/wiki/1-Hexyne

    1-Hexyne is a hydrocarbon consisting of a straight six-carbon chain having a terminal alkyne. Its molecular formula is HC 2 C 4 H 9. A colorless liquid, it is one of three isomers of hexyne. [1] It is used as a reagent in organic synthesis.

  7. Isomerization - Wikipedia

    en.wikipedia.org/wiki/Isomerization

    The compound with the formula (C 5 H 5) 2 Fe 2 (CO) 4 exists as three isomers in solution. In one isomer the CO ligands are terminal. When a pair of CO are bridging, cis and trans isomers are possible depending on the location of the C 5 H 5 groups. [7] Another example in organometallic chemistry is the linkage isomerization of ...

  8. Open-chain compound - Wikipedia

    en.wikipedia.org/wiki/Open-chain_compound

    [2] [3] Many of the simple molecules of organic chemistry, such as the alkanes and alkenes, have both linear and ring isomers, that is, both acyclic and cyclic. For those with 4 or more carbons, the linear forms can have straight-chain or branched-chain isomers.

  9. Isomer - Wikipedia

    en.wikipedia.org/wiki/Isomer

    In chemistry, isomers are molecules or polyatomic ions with identical molecular formula – that is, the same number of atoms of each element – but distinct arrangements of atoms in space. [1] Isomerism refers to the existence or possibility of isomers. Isomers do not necessarily share similar chemical or physical properties.
