In naming simple alcohols, the name of the alkane chain loses the terminal e and adds the suffix -ol, e.g., as in "ethanol" from the alkane chain name "ethane". [19] 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.

The carbon chains in plant alkanes are usually odd-numbered, between 27 and 33 carbon atoms in length, [40] and are made by the plants by decarboxylation of even-numbered fatty acids. The exact composition of the layer of wax is not only species-dependent but also changes with the season and such environmental factors as lighting conditions ...
A three-carbon chain with the -OH on the second carbon would be propan-2-ol. Note that in some instances, common names are better. If the -OH is on the end of the chain, or the carbon chain is only 1 or 2, use no number. Use standard Greek prefixes to name molecules with two or more -OH groups (di- for 2, and so on). [1]
Hydrocarbon prefixes: These prefixes indicate the number of carbon atoms in a straight-chain alkane. Some examples include: meth- (1 carbon) eth- (2 carbons) prop- (3 carbons) but- (4 carbons) pent- (5 carbons) hex- (6 carbons) Alkyl group prefixes: These prefixes are used to name alkyl groups (chains of carbon atoms) that are attached to ...
1-Butanol, also known as butan-1-ol or n-butanol, is a primary alcohol with the chemical formula C 4 H 9 OH and a linear structure. Isomers of 1-butanol are isobutanol, butan-2-ol and tert-butanol. The unmodified term butanol usually refers to the straight chain isomer.
