Same Molecural Formula, different structural formula = Structural Isomerism (: Formula: C 5 H 1 2 Molecular mass: 72.2 Boiling point: 9.5°C Melting point: -16.6°C Density (at 20°C): 0.61 g/cm³ Flash point: -7°C Auto-ignition temperature: 450°C Explosive limits, vol% in air: 1.3 - 7.5 Solubility in water: none Vapour pressure, kPa at 20°C: 146 Relative vapour density (air = 1): 2.5 Neopentane, also called dimethylpropane or 2,2-dimethylpropane, is a double-branched-chain alkane with five carbon atoms. Neopentane is an 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. Pentane (C 5 H 12) has three structural isomers. Isomer 1 is n-pentane, the straight chain normal structure for pentane. Isomer 2 is 2-methylbutane, a branched chain with a carbon* atom joined onto three other carbon atoms. Isomer 3 is 2,2-dimethylpropane, a branched chain with the central carbon* atom joined onto four other carbon atoms. Note ...
