Butane is also used as a collective term for n -butane together with its only other isomer, isobutane (also called methylpropane), CH (CH 3) 3 . Butanes are highly flammable, colorless, easily liquefied gases.

(Note: n-butane, n butane and butane are all the same thing as are isobutane and i-butane) The difference between n butane and isobutane (isobutane vs butane) is minimal. The only notable differences are in boiling temperature, vapour pressure and the arrangement of their atoms, even though isobutane and n butane have the same chemical formula: C 4 H 10 .
