Butene reacts with water to produce butanol, and with hydrogen to produce butane. In addition, it forms various addition polymers.
*Butane
Boiling point: 0.5ºC Melting point: -138.5ºC
Butane is the smallest alkane that has isomers, one of them being methylpropane (isobutane). Butane is used as fuel for lighters and portable stoves.
Properties
Combustible gas with a characteristic odor that is colorless at ambient temperature and pressure
