  3. Alkyne - Wikipedia

    en.wikipedia.org/wiki/Alkyne

    Alkynes having four or more carbon atoms can form different structural isomers by having the triple bond in different positions or having some of the carbon atoms be substituents rather than part of the parent chain. Other non-alkyne structural isomers are also possible. C 2 H 2: acetylene only; C 3 H 4: propyne only; C 4 H 6: 2 isomers: 1 ...

  5. Open-chain compound - Wikipedia

    en.wikipedia.org/wiki/Open-chain_compound

    For example, in living organisms, the open-chain isomer of glucose usually exists only transiently, in small amounts; D-glucose is the usual isomer; and L-glucose is rare. Straight-chain molecules are often not literally straight, in the sense that their bond angles are often not 180°, but the name reflects that they are schematically straight.

  6. 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 ...

  7. Cycloisomerization - Wikipedia

    en.wikipedia.org/wiki/Cycloisomerization

    Enyne cycloisomerization, an alkyne variant of the Alder-ene reaction (figure 5), is an intramolecular rearrangement of 1,n–enynes to give the corresponding cyclic isomer. Although the rearrangement may occur under thermal conditions, the scope of the thermal rearrangement is limited due to the requirement of high temperatures, thus ...

    en.wikipedia.org/wiki/Octyne

    Octynes are alkynes with one triple bond and the molecular formula C 8 H 14. The isomers are: 1-Octyne; 2-Octyne; 3-Octyne; 4-Octyne This page was last ...

  9. Syn and anti addition - Wikipedia

    en.wikipedia.org/wiki/Syn_and_anti_addition

    In organic chemistry, syn-and anti-addition are different ways in which substituent molecules can be added to an alkene (R 2 C=CR 2) or alkyne (RC≡CR).The concepts of syn and anti addition are used to characterize the different reactions of organic chemistry by reflecting the stereochemistry of the products in a reaction.
