WebDifferent isomers of octane can contribute to a lower or higher octane rating. For example, n -octane (the straight chain of 8 carbon atoms with no branching) has a -20 (negative) Research Octane Rating, whereas pure iso-octane has an RON rating of 100. Some fuels have an octane rating higher than 100, notably those containing methanol or ethanol. WebSep 24, 2024 · The four carbons can be drawn in a row to form butane or the can branch to form isobutane. The two compounds have different properties—for example, butane boils at −0.5°C, while isobutane boils at −11.7°C. Likewise the molecular formula: C 5 H 12 has three possible isomer.
