Number of isomers [3] [4] Number of isomers including stereoisomers [3] [5] Molecular Formula Name of straight chain Synonyms 1 1 1 CH 4: methane: methyl hydride; natural gas 2 1 1 C 2 H 6: ethane: dimethyl; ethyl hydride; methyl methane 3 1 1 C 3 H 8: propane: dimethyl methane; propyl hydride 4 2 2 C 4 H 10: n-butane: butyl hydride ...
They separated the reaction products into two isomers, with melting points 210C (tetrabenzoate: 146C) and 187C (tetrabenzoate: 260C), respectively, in 1:2 ratio. [5] In 1953, Théodore Posternak and H. Friedli obtained the achiral 1,4/2,3 isomer and racemic mixtures of the 1,2/3,4, 1,3/2,4, and 1,2,4/3 isomers. By biochemical oxydation, they ...
This is the list of the 75 isomers of decane. [1] [2] Straight-chain. n-Decane; Nonane. 2-Methylnonane; 3-3-Methylnonane; 4-Methylnonane; 5-Methylnonane; Octane
There are several cyclohexanetetrol isomers that differ on the position of the hydroxyl groups along the ring, and on their orientation relative to the mean plane of the ring. The isomers with each hydroxyl on a distinct carbon are: [9] 1,2,3,4-Cyclohexanetetrol or ortho- (10 isomers, including 4 enantiomer pairs) [1] [10]
In chemistry, isomers are molecules or polyatomic ions with identical molecular formula – that is, the same number of atoms of each element – but distinct arrangements of atoms in space. [1] Isomerism refers to the existence or possibility of isomers.

Functional isomers are structural isomers which have different functional groups, resulting in significantly different chemical and physical properties. [ 11 ] An example is the pair propanal H 3 C–CH 2 –C(=O)-H and acetone H 3 C–C(=O)–CH 3 : the first has a –C(=O)H functional group, which makes it an aldehyde , whereas the second has ...
