What is the IUPAC nomenclature of H2S2O7? Write the structural formulae of the two isomers with the molecular formula #C_4H_8O# to What are the four structural isomers of the alcohol with molecular formula C4H9OH. We use cookies on our website to give you the most relevant experience by remembering your preferences and repeat visits. The anti-knock rating of this mixture would be the same as the percentage of iso-octane in the mix. Remember that it is possible to draw each isomer in several different ways and you may inadvertently count the same isomer more than once. All isomers of octane have the same molecular formula. However, a molecule with 5-7 constitutional isomers is a fair game! Less stable fuel, below 90 octane, is fine for most engines. 3 How many isomers of octane is possible?
