Methylpentene is an alkene with a molecular formula C 6 H 12.The prefix "methyl-" is derived from the fact that there is a methyl(CH 3) branch, the word root "-pent-" is derived from the fact that there are 5 carbon atoms in the parent chain, while the "-ene" suffix denotes that there is a double bond present, as per IUPAC nomenclature. [1]
3-Methylpentane is a branched alkane with the molecular formula C 6 H 14. It is a structural isomer of hexane composed of a methyl group bonded to the third carbon atom in a pentane chain. It is of similar structure to the isomeric 2-methylpentane, which has the methyl group located on the second carbon of the pentane chain.
As of early 1990s, it was present in American [4] and European [5] gasoline in small amounts, and by 2011 its share in US gas varied between 2 and 8%. [6] Using a quantitative structure-activity relationship (QSAR) prediction model, 2-Methylpentane has a research octane number (RON) of 75, motor octane number (MON) of 77, and cetane number (CN ...

It consists of several isomeric compounds having the formula C 6 H 10. The linear and branched members are: 1-Hexyne (n-butylacetylene) 2-Hexyne (methylpropylacetylene)
Constitution formula for isomers of C 5 H 8 with CAS numbers. The molecular formula C 5 H 8 may refer to any of the following hydrocarbons: . Pentynes:; 1-Pentyne; 2-Pentyne; 3-Methyl-1-butyne or isopentyne, CAS 598-23-2
The branched isomers are 2-methylbut-1-ene, 3-methylbut-1-ene (isopentene), and 2-methylbut-2-ene (isoamylene). Isoamylene is one of the three main byproducts of deep catalytic cracking (DCC), which is very similar to the operation of fluid catalytic cracking (FCC).
The optical center is the middle carbon of the pentane backbone, which is connected to one hydrogen atom, one methyl group, one ethyl group – C 2 H 5, and one isopropyl group – CH(CH 3) 2. The two enantiomers are denoted (3R)-2,3-dimethylpentane and (3S)-2,3-dimethylpentane (the other simplest chiral alkane is its structural isomer 3 ...
