Below is a list of the boiling and melting points of various alkenes with the corresponding alkane and alkyne analogues. ... −165.2: −90.0 Boiling point: 36: 29.9 ...
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.

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.
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.
But-2-ene is an acyclic alkene with four carbon atoms. It is the simplest alkene exhibiting cis / trans -isomerism (also known as (E / Z)-isomerism); that is, it exists as two geometric isomers cis -but-2-ene ( (Z)-but-2-ene) and trans- but-2-ene ( (E)-but-2-ene). It is a petrochemical, produced by the catalytic cracking of crude oil or the ...
2 C 6 H 12 + O 2 → 2 C 6 H 11 OH. This process coforms cyclohexanone, and this mixture ("KA oil" for ketone-alcohol oil) is the main feedstock for the production of adipic acid, used to make nylon. The small cycloalkanes – in particular, cyclopropane – have a lower stability due to Baeyer strain and ring strain.
Higher alkanes are alkanes having nine or more carbon atoms. Nonane is the lightest alkane to have a flash point above 25 °C, and is not classified as dangerously flammable. [according to whom?] The term higher alkanes is sometimes used literally as "alkanes with a higher number of carbon atoms". One definition distinguishes the higher alkanes ...
