Butan-2-ol, or sec-butanol, is an organic compound with formula C H 3 CH(OH)CH 2 CH 3. Its structural isomers are 1-butanol , isobutanol , and tert -butanol . 2-Butanol is chiral and thus can be obtained as either of two stereoisomers designated as ( R )-(−)-butan-2-ol and ( S )-(+)-butan-2-ol.
Butanol (also called butyl alcohol) is a four-carbon alcohol with a formula of C 4 H 9 O H, which occurs in five isomeric structures (four structural isomers), from a straight-chain primary alcohol to a branched-chain tertiary alcohol; [1] all are a butyl or isobutyl group linked to a hydroxyl group (sometimes represented as BuOH, sec-BuOH, i-BuOH, and t-BuOH).

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. 1-Butanol occurs naturally as a minor product of the ethanol fermentation ...

tert-Butyl alcohol is the simplest tertiary alcohol, with a formula of (CH 3) 3 COH (sometimes represented as t-BuOH).Its isomers are 1-butanol, isobutanol, and butan-2-ol. tert-Butyl alcohol is a colorless solid, which melts near room temperature and has a camphor-like odor.
In organic chemistry, butyl is a four-carbon alkyl radical or substituent group with general chemical formula −C 4 H 9, derived from either of the two isomers (n-butane and isobutane) of butane. The isomer n -butane can connect in two ways, giving rise to two "-butyl" groups:
