Isobutane, also known as i-butane, 2-methylpropane or methylpropane, is a chemical compound with molecular formula HC(CH 3) 3. It is an isomer of butane. Isobutane is a colorless, odorless gas. It is the simplest alkane with a tertiary carbon atom.
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.
There are two stable structural isomers: 2-methylpropane-1,2-diol; 2-methylpropane-1,3-diol; and one unstable geminal diol: 2-methylpropane-1,1-diol (not a glycol), hydrate of 2-methylpropanal (isobutyraldehyde) These three methylpropanediols are structural isomers of butanediols. They are not chiral.
Butane exists as two isomers, n-butane with connectivity CH 3 CH 2 CH 2 CH 3 and iso-butane with the formula (CH 3) ... methylpropane: Molecular diagram Skeletal diagram

2 (C 2 H 5). Isopentane is a volatile and flammable liquid. It is one of three structural isomers with the molecular formula C 5 H 12, the others being pentane (n-pentane) and neopentane (2,2-dimethylpropane). Isopentane is commonly used in conjunction with liquid nitrogen to achieve a liquid bath temperature of −160 °C.

The number of possible isomers increases rapidly with the number of carbon atoms. For example, for acyclic alkanes: [3] C 1: methane only; C 2: ethane only; C 3: propane only; C 4: 2 isomers: butane and isobutane; C 5: 3 isomers: pentane, isopentane, and neopentane; C 6: 5 isomers: hexane, 2-methylpentane, 3-methylpentane, 2,2-dimethylbutane ...
