Chemical compound
2-Methyloctane is a branched alkane hydrocarbon with the chemical formula C9 H20 . It is a colorless, flammable liquid
Combustion reactions
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.
C 9 H 20 + 14 O2 → 9 CO2 + 10 H2 O
When insufficient oxygen is present for complete combustion, carbon monoxide is produced.
2 C9 H20 + 19 O2 → 18 CO + 20 H2 O
