  4. Pentene - Wikipedia

    en.wikipedia.org/wiki/Pentene

    1-Pentene is an alpha-olefin.Most often, 1-pentene is made as a byproduct of catalytic or thermal cracking of petroleum or during the production of ethylene and propylene via thermal cracking of hydrocarbon fractions.

  5. Electrocyclic reaction - Wikipedia

    en.wikipedia.org/wiki/Electrocyclic_reaction

    The cis isomer exclusively yields cis,trans-hexa-2,4-diene whereas the trans isomer gives the trans,trans diene: [2] This reaction course can be explained in a simple analysis through the frontier-orbital method : the sigma bond in the reactant will open in such a way that the resulting p-orbitals will have the same symmetry as the HOMO of the ...

  6. Hydroformylation - Wikipedia

    en.wikipedia.org/wiki/Hydroformylation

    Hydroformylation of an alkene (R 1 to R 3 organyl groups (i. e. alkyl-or aryl group) or hydrogen). In organic chemistry, hydroformylation, also known as oxo synthesis or oxo process, is an industrial process for the production of aldehydes (R−CH=O) from alkenes (R 2 C=CR 2).

  7. Cis–trans isomerism - Wikipedia

    en.wikipedia.org/wiki/Cis–trans_isomerism

    Because the cis–trans and E–Z systems compare different groups on the alkene, it is not strictly true that Z corresponds to cis and E corresponds to trans. For example, trans-2-chlorobut-2-ene (the two methyl groups, C1 and C4, on the but-2-ene backbone are trans to each other) is (Z)-2-chlorobut-2-ene (the chlorine and C4 are together ...

    This article gives a list of conversion factors for several physical quantities.A number of different units (some only of historical interest) are shown and expressed in terms of the corresponding SI unit.

  9. Alkyne - Wikipedia

    en.wikipedia.org/wiki/Alkyne

    In acetylene, the H–C≡C bond angles are 180°. By virtue of this bond angle, alkynes are rod-like. Correspondingly, cyclic alkynes are rare. Benzyne cannot be isolated. . The C≡C bond distance of 118 picometers (for C 2 H 2) is much shorter than the C=C distance in alkenes (132 pm, for C 2 H 4) or the C–C bond in alkanes (153 p
