| Isopentane | Neopentane |
|---|---|
| IUPAC name: 2-Methylbutane | IUPAC name: 2,2-Dimethylpropane |
| One branched chain | Highly branched structure |
| Less symmetrical | More symmetrical |
| Formula: C₅H₁₂ | Formula: C₅H₁₂ |
Both are structural isomers of pentane (C₅H₁₂), meaning they have the same molecular formula but different carbon arrangements.
Quick Fact: Pentane has three structural isomers: n-pentane, isopentane, and neopentane.
