AKA Paraffins, are chemical compounds that consist only of the elements carbon (C) and hydrogen (H). Each are linked by a single bond.
Each carbon atom must have 4 bonds (either C-H or C-C bonds), and each hydrogen atom must be joined to a carbon atom (H-C bonds).
General formula C n H 2n+2 (Linear saturated hydrocarbon)

n-pentane - A component of natural gas, lighter and blowtorch fuels and aerosol propellants, consists of five carbon atoms and twelve hydrogen atoms C 5 H 12 2-methylbutane - Isopentane is an extremely volatile and extremely flammable liquid at room temperature and pressure. 2-Methylbutane commonly used in conjunction with liquid nitrogen to achieve a liquid bath temperature of -160 °C.

2,2-dimethylpropane (neopentane): One of three structural isomers with the molecular formula C 5 H 12 , the others being pentane and isopentane. Extremely 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.
