As of 2010s, the only commercial manufacturer of 1-pentene was Sasol Ltd., where it is separated from crude by the Fischer-Tropsch process. [2] 2-Pentene has two geometric isomers: cis-2-pentene and trans-2-pentene. Cis-2-Pentene is used in olefin metathesis.
For example, there are two isomers of square planar Pt(NH 3) 2 Cl 2, as explained by Alfred Werner in 1893. The cis isomer, whose full name is cis -diamminedichloroplatinum(II), was shown in 1969 by Barnett Rosenberg to have antitumor activity, and is now a chemotherapy drug known by the short name cisplatin .
Pentane is an organic compound with the formula C 5 H 12 —that is, an alkane with five carbon atoms. The term may refer to any of three structural isomers, or to a mixture of them: in the IUPAC nomenclature, however, pentane means exclusively the n-pentane isomer, in which case pentanes refers to a mixture of them; the other two are called isopentane (methylbutane) and neopentane ...
9 – MgBr with acetone to form 2,3-dimethyl-2-pentanol, then dehydrating this alcohol to form 2,3-dimethyl-2-pentene, and hydrogenating this product. [ 4 ] The isomer is present at about 2.4% by weight in the hydrocarbon mixture obtained by the condensation of methanol at 200 °C with a zinc iodide catalyst (the main component of the mixture ...
A simple example of cis–trans isomerism is the 1,2-disubstituted ethenes, like the dichloroethene (C 2 H 2 Cl 2) isomers shown below. [7] Dichloroethene isomers. Molecule I is cis-1,2-dichloroethene and molecule II is trans-1,2-dichloroethene.

Pentyl is a five-carbon alkyl group or substituent with chemical formula-C 5 H 11.It is the substituent form of the alkane pentane.. In older literature, the common non-systematic name amyl was often used for the pentyl group.
An example of a common name is terpineol, the name of which can tell us only that it is an alcohol (because the suffix "-ol" is in the name) and it should then have a hydroxyl group (–OH) attached to it. The IUPAC naming system for organic compounds can be demonstrated using the example provided in the adjacent image.
