  2. Alkene - Wikipedia

    en.wikipedia.org/wiki/Alkene

    Alkene. In organic chemistry, an alkene, or olefin, is a hydrocarbon containing a carbon –carbon double bond. [1] The double bond may be internal or in the terminal position. Terminal alkenes are also known as α-olefins. The International Union of Pure and Applied Chemistry (IUPAC) recommends using the name "alkene" only for acyclic ...

    These differences can be very small, as in the case of the boiling point of straight-chain alkenes, such as pent-2-ene, which is 37 °C in the cis isomer and 36 °C in the trans isomer. [5] The differences between cis and trans isomers can be larger if polar bonds are present, as in the 1,2-dichloroethenes.

  5. Alkane - Wikipedia

    en.wikipedia.org/wiki/Alkane

    Alkane. In organic chemistry, an alkane, or paraffin (a historical trivial name that also has other meanings), is an acyclic saturated hydrocarbon. In other words, an alkane consists of hydrogen and carbon atoms arranged in a tree structure in which all the carbon–carbon bonds are single. [1] Alkanes have the general chemical formula CnH2n+2.

    en.wikipedia.org/wiki/1-Octadecene

    Infobox references. 1-Octadecene is a long-chain hydrocarbon and an alkene with the molecular formula CH 2 =CH (CH 2) 15 CH 3. It is one of many isomers of octadecene. Classified as an alpha-olefin, 1-octadecene is the longest alkene that is liquid at room temperature. [3][2]

  7. Boiling point - Wikipedia

    en.wikipedia.org/wiki/Boiling_point

    Water boiling at 99.3 °C (210.8 °F) at 215 m (705 ft) elevation. The boiling point of a substance is the temperature at which the vapor pressure of a liquid equals the pressure surrounding the liquid [1] [2] and the liquid changes into a vapor. The boiling point of a liquid varies depending upon the surrounding environmental pressure.

    Boiling point: 80.1 °C (176.2 °F; 353.2 K) ... for producing ethylene and other alkenes from aliphatic ... can also occur through contact with contaminated water.

  9. 1-Octene - Wikipedia

    en.wikipedia.org/wiki/1-Octene

    1-Octene is an organic compound with a formula CH 2 CHC 6 H 13. The alkene is classified as a higher olefin and alpha-olefin, meaning that the double bond is located at the alpha (primary) position, endowing this compound with higher reactivity and thus useful chemical properties. 1-Octene is one of the important linear alpha olefins in industry.
