Typical products created with isobutane are 2,4-dimethylpentane and especially 2,2,4-trimethylpentane. Constitutional Isomers, also known as structural isomers, are connected differently and have different bonding sequences. For example, the molecular formula C 4 H 10 tells us there are 4 carbon atoms and 10 hydrogen atoms in a molecule, but it doesn't distinguish between butane and isobutane. For example, the condensed formula of butane is CH 3 CH 2 CH 2 CH 3, and that of 2-chloropropane is (CH 3) 2 CHCl.
