Neopentane

Common card · No. 497268

Neopentane, also called 2,2-dimethylpropane, is a double-branched-chain alkane with five carbon atoms, with the chemical formula C(CH3)4. 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. Neopentane is the simplest alkane with a quaternary carbon, and has achiral tetrahedral symmetry. It is one of the three structural isomers with the molecular formula C5H12 (pentanes), the other two being n-pentane and isopentane. Out of these three, it is the only one to be a gas at standard conditions; the others are liquids. It was first synthesized by Russian chemist Mikhail Lvov in 1870.
