WebList of isomers of nonane This is the list of structural isomers of nonane. In comparison, spontaneous combustion, also called auto-ignition, detonation, or knock, happens when rising temperature and pressure from the primary combustion causes unburned fuel to ignite. This measurement is taken by adjusting the octane engine's cylinder height, which changes the compression ratio/pressure in the engine until the knocking reaches a specific intensity level. name for all 18 isomers with the formula C8 H18 . Using this formula, we can write a molecular formula for any alkane with a given number of carbon atoms.
