A cyclohexane molecule in chair conformation. Hydrogen atoms in axial positions are shown in red, while those in equatorial positions are in blue. Cyclohexane conformations are any of several three-dimensional shapes adopted by molecules of cyclohexane. Because many compounds feature structurally similar six-membered rings, the structure and ...

1,2-Dimethylcyclopropane is a cycloalkane consisting of a cyclopropane ring substituted with two methyl groups attached to adjacent carbon atoms. [1] It has three stereoisomers, one cis -isomer and a pair of trans - enantiomers, which differ depending on the orientation of the two methyl groups. As with other cyclopropanes, ring tension results ...
Cayley table as general (and special) linear group GL (2, 2) In mathematics, D3 (sometimes alternatively denoted by D6) is the dihedral group of degree 3 and order 6. It equals the symmetric group S3. It is also the smallest non-abelian group. [ 1 ] This page illustrates many group concepts using this group as example.
Structural isomer. In chemistry, a structural isomer (or constitutional isomer in the IUPAC nomenclature [ 1 ]) of a compound is another compound whose molecule has the same number of atoms of each element, but with logically distinct bonds between them. [ 2 ][ 3 ] The term metamer was formerly used for the same concept. [ 4 ]
trans -but-2-ene. Cis–trans isomerism, also known as geometric isomerism, describes certain arrangements of atoms within molecules. The prefixes " cis " and " trans " are from Latin: "this side of" and "the other side of", respectively. [ 1 ] In the context of chemistry, cis indicates that the functional groups (substituents) are on the same ...
CH 3 C 6 H 5 + 3 H 2 → CH 3 C 6 H 11. Methylcyclohexane, as a component of a mixture, is usually dehydrogenated to toluene, which increases the octane rating of gasoline. [4] The conversion of methylcyclohexane to toluene is a classic aromatization reaction. This platinum (Pt)-catalyzed process is practiced on scale in the production of ...
Alkyl cycloalkanes are chemical compounds with an alkyl group with a single ring of carbons to which hydrogens are attached according to the formula. C n H 2n. They are named analogously to their normal alkane counterpart of the same carbon count: methylcyclopropane, methylcyclobutane, methylcyclopentane, methylcyclohexane, etc. [1 ...
