Ethanol (also called ethyl alcohol, grain alcohol, drinking alcohol, or simply alcohol) is an organic compound with the chemical formula CH 3 CH 2 OH.It is an alcohol, with its formula also written as C 2 H 5 OH, C 2 H 6 O or EtOH, where Et stands for ethyl.
When necessary, the position of the hydroxyl group is indicated by a number between the alkane name and the -ol: propan-1-ol for CH 3 CH 2 CH 2 OH, propan-2-ol for CH 3 CH(OH)CH 3. If a higher priority group is present (such as an aldehyde , ketone , or carboxylic acid ), then the prefix hydroxy- is used, [ 19 ] e.g., as in 1-hydroxy-2 ...
The systematic IUPAC name is not always the preferred IUPAC name, for example, lactic acid is a common, and also the preferred, name for what systematic rules call 2-hydroxypropanoic acid. This list is ordered by the number of carbon atoms in a carboxylic acid.
This is a free rotation only in the simplest cases like gaseous methyl chloride CH 3 Cl. In most molecules, the remainder R breaks the C ∞ symmetry of the R−C axis and creates a potential V(φ) that restricts the free motion of the three protons. For the model case of ethane CH 3 CH 3, this is discussed under the name ethane barrier. In ...

The shorter of the two chains becomes the first part of the name with the -ane suffix changed to -oxy, and the longer alkane chain becomes the suffix of the name of the ether. Thus, CH 3 OCH 3 is methoxymethane, and CH 3 OCH 2 CH 3 is methoxyethane (not ethoxymethane). If the oxygen is not attached to the end of the main alkane chain, then the ...
An example is the condensed molecular/chemical formula for ethanol, which is CH 3 −CH 2 −OH or CH 3 CH 2 OH. However, even a condensed chemical formula is necessarily limited in its ability to show complex bonding relationships between atoms, especially atoms that have bonds to four or more different substituents .
1-Hexanol (IUPAC name hexan-1-ol) is an organic alcohol with a six-carbon chain and a condensed structural formula of CH 3 (CH 2) 5 OH. This colorless liquid is slightly soluble in water, but miscible with diethyl ether and ethanol.
