Isopentane vs. Neopentane

Isopentanenoun

(organic compound) An aliphatic hydrocarbon with the chemical structure CH2CH2CH(CH3)2; isomeric with pentane and neopentane.

Isopentane

Isopentane, also called methylbutane or 2-methylbutane, is a branched-chain saturated hydrocarbon (an alkane) with five carbon atoms, with formula C5H12 or CH(CH3)2(C2H5). Isopentane is an extremely volatile and extremely flammable liquid at room temperature and pressure.

Neopentanenoun

(organic compound) The aliphatic alkane 2,2-dimethylpropane; isomeric with pentane and isopentane

Neopentane

Neopentane, also called 2,2-dimethylpropane, is a double-branched-chain alkane with five carbon atoms. Neopentane is a flammable gas at room temperature and pressure which can condense into a highly volatile liquid on a cold day, in an ice bath, or when compressed to a higher pressure.
