However, a chemical equation usually describes a chemical reaction, not just a single molecule. If you'd like to see an equation involving isobutane, please provide the following information:
* What is the reaction you're interested in? (e.g., combustion, isomerization, etc.)
* What are the reactants and products?
For example, if you want the combustion reaction of isobutane, the equation would be:
2 C₄H₁₀ + 13 O₂ → 8 CO₂ + 10 H₂O
Let me know what you need, and I can help you with the equation!
