2-methylpropane
2-methylpropane is an organic compound made up of hydrogen and carbon. Its carbon chain is 3 carbons long that are all attached to hydrogens and the second carbon along is attached to a methyl group[1]. Also known as i-butane, occupying the chemical formula HC(CH3)3, is the simplest alkane with a tertiary carbon. I-butane is a precursor molecule in the petrochemical industry, such as the production of isooctane. The production of isooctane is useful because it is used as a fuel. 2-methylpropane is useful to chemical engineers because not only is it used in chemical synthesis of useful fuels, but it has a relatively low vapour density (21 degrees Celcius) which means it can be stored easily and safely[2]. On the contrary, 2-methylpropane should be handled with caution, such as eyeshields and gloves should be used.
