which alkane is the isomer of butane called 2-methylpropane
Isobutane Isobutane, also known as i-butane or methylpropane, is a chemical compound with molecular formula C 4H 10 and is an isomer of butane. It is the simplest alkane with a tertiary carbon. Isobutane is used as a feedstock in the petrochemical industry, for example in the synthesis of isooctane.[5]
Chemical formula For polymers in condensed chemical formulas, parentheses are placed around the repeating unit. For example, a hydrocarbon molecule that is described as CH3(CH2)50CH3, is a molecule with fifty repeating units. If the number of repeating units is unknown or variable, the letter n may be used to indicate this formula: CH3(CH2)nCH3.
