Structural isomers are compounds with the same molecular formula but different arrangements of atoms. Pentane has the molecular formula C₅H₁₂. The three structural isomers of pentane are: 1. n- pentane (a straight chain of five carbon atoms). 2. Isopentane (2-methylbutane, a four-carbon chain with a methyl group attached to the second carbon).
The number of structural isomers of pentane is
