The prefix "iso" or "iso" means "isolated" while the prefix 'n-' stands for "normal". Butan-2-yl (sec-butyl) group is chiral. The carbon atom at position 2 is a stereocenter. It has four different groups attached: −H, −CH 3, −CH 2 −CH 3, and −R (the R group is not equal to those three groups).
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).
The terms sec and tert are considered obsolete and should only be used for unsubstituted sec-butoxy, sec-butyl [26] [27] or tert-butyl groups. [ 28 ] [ 27 ] There are various spellings such as "sec-butyl", "s-butyl", "sBu" or "bus" which are also considered obsolete.
Isobutylene (or 2-methylpropene) is a hydrocarbon with the chemical formula (CH 3) 2 C=CH 2. It is a four-carbon branched alkene (olefin), one of the four isomers of butylene . It is a colorless flammable gas, and is of considerable industrial value.

Methyl isobutyl ketone (MIBK, 4-methylpentan-2-one) is an organic compound with the condensed chemical formula (CH 3) 2 CHCH 2 C(O)CH 3. This ketone is a colourless liquid that is used as a solvent for gums, resins, paints, varnishes, lacquers, and nitrocellulose.
n-Butyl acetate is an organic compound with the formula CH 3 CO 2 (CH 2) 3 CH 3. A colorless, flammable liquid, it is the ester derived from n- butanol and acetic acid . It is found in many types of fruit, where it imparts characteristic flavors and has a sweet smell of banana or apple.
Isobutylamine is an organic chemical compound (specifically, an amine) with the formula (CH 3) 2 CHCH 2 NH 2, and occurs as a colorless liquid. [1] [2] Isobutylamine is one of the four isomeric amines of butane, the others being n-butylamine, sec-butylamine and tert-butylamine.
