Typical agents[edit] ’The typical antiknock agents in use are: Tetraethyllead (Still in use as a high octane additive) Methylcyclopentadienyl manganese tricarbonyl (MMT) Ferrocene Iron pentacarbonyl Toluene Isooctane Tetraethyllead[edit] A side effect of the lead additives was protection of the valve seats from erosion. Many classic cars’ engines have needed modification to use lead-free fuels since leaded fuels became unavailable

Arenes The aromatic hydrocarbons also have the name arenes. They contain in their molecule one or more cycles made up from 6 carbon atoms. When the molecule is formed out of a single cycle‚ the hydrocarbons are mono nucleuses; when the molecule contains more than one cycle‚ the hydrocarbons are poly nucleuses. The simplest aromatic hydrocarbon‚ benzene‚ is compound out of just one such cycle; its formula is C6H6. The representation of benzene through a cycle of 6 carbon atoms with 3 double bounds
