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 abundance of water on the Moon's surface was inferred to be equivalent to the contents of a 12-ounce bottle of water per cubic meter of lunar soil. [ 9 ] The Chang'e 5 probe, which landed on the Moon on 1 December 2020, carried a mineralogical spectrometer that could measure infrared reflectance spectra of lunar rock and regolith.
Erythritol is a sugar alcohol. It is 60–70% as sweet as sugar and almost noncaloric. It is 60–70% as sweet as sugar and almost noncaloric. Sugar alcohols (also called polyhydric alcohols , polyalcohols , alditols or glycitols ) are organic compounds , typically derived from sugars , containing one hydroxyl group (−OH) attached to each ...
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. Ethanol is a volatile, flammable, colorless liquid with a characteristic wine-like ...
Skeletal structural formula of Vitamin B 12. Many organic molecules are too complicated to be specified by a molecular formula . The structural formula of a chemical compound is a graphic representation of the molecular structure (determined by structural chemistry methods), showing how the atoms are connected to one another.

The conversion of ethanol to ethylene is a fundamental example: [3] [4] CH 3 CH 2 OH → H 2 C=CH 2 + H 2 O. The reaction is accelerated by acid catalysts such as sulfuric acid and certain zeolites. These reactions often proceed via carbocation intermediates as shown for the dehydration of cyclohexanol. [5] Some alcohols are prone to dehydration.
Dextrose monohydrate is the hydrated form of D-glucose, meaning that it is a glucose molecule with an additional water molecule attached. [38] Its chemical formula is C 6 H 12 O 6 · H 2 O. [38] [39] Dextrose monohydrate is also called hydrated D-glucose, and commonly manufactured from plant starches.
The chemical equations below summarize the fermentation of sucrose (C 12 H 22 O 11) into ethanol (C 2 H 5 OH). Alcoholic fermentation converts one mole of glucose into two moles of ethanol and two moles of carbon dioxide, producing two moles of ATP in the process. C 6 H 12 O 6 + 2 ADP + 2 P i → 2 C 2 H 5 OH + 2 CO 2 + 2 ATP
