8. 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.
