Octane has many structural isomers that differ by the location of branching in the carbon chain. One of these isomers, 2,2,4-trimethylpentane (commonly called iso-octane), is used as one of the standard values in the octane rating scale. Octane is a component of gasoline and petroleum.

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 ...
The molecular formula C 3 H 6 O may refer to: . Chemistry portal; Alcohols. Allyl alcohol or 2-propen-1-ol, CH 2 =CH-CH 2 OH, CAS number 107-18-6; cyclopropanol or cyclopropyl alcohol, cyclo (-CH 2-CH 2-HOHC-), CAS number 16545-68-9
Discounting isomers that are equivalent under rotations, there are nine isomers that differ by this criterion, and behave as different stable substances (two of them being enantiomers of each other). The most common one in nature ( myo -inositol) has the hydroxyls on carbons 1, 2, 3 and 5 on the same side of that plane, and can therefore be ...
The valence isomers are not restricted to isomers of benzene. Valence isomers are also seen in the series (CH) 8. Due to the larger number of units, the number of possible valence isomers is also greater and at least 21: Valence isomers of cyclooctatetraene
Carboxylic acids are organic acids characterized by a carboxyl (-COOH) functional group. The naming of these compounds is governed by IUPAC nomenclature, which ensures systematic and consistent naming of chemicals.
