2-Methyloctane is a branched alkane hydrocarbon with the chemical formula C<sub>9</sub>H<sub>20</sub>. It is a colorless, flammable liquid
2-Methyloctane burns in the same way as other alkanes. Where there is enough oxygen, nonane burns to form water and carbon dioxide, so 2-methyloctane would do the same.
When insufficient oxygen is present for complete combustion, carbon monoxide is produced.
