Octane is a straight-chain alkane which includes 8 carbon atoms. Octane is a colourless liquid with the odour of gasoline. It is an organic chemical compound and is a chief element of gasoline (petrol). It is a volatile and highly flammable colourless liquid. Octane features 18 isomers and 2, 2, 4-trimethylpentane also known isooctane is one of the main isomers of octane. Let us know the chemical composition and other details.
