Close
the chemical structure shows it is a branched-chain alkane with the molecular formula C10H22. Its consists of a nine-carbon straight chain (nonane) with a methyl group (-CH3) attached to the second carbon atom.

Its physical state is liquid and appears colorless. It smells of petroleum distillates. May be fatal if swallowed and enters airways. It is a category 3 flammable liquid and has a category 1 aspiration toxicity. 2-Methylnonane is insoluble and floats on water and evaporates slowly.[2]

2-Methylnonane is achiral as it lacks a chiral center; that is, it is an asymmetrical molecule and it cannot be superimposed on its mirror image. It represents the first among the four monomethyl nonane isomers.[3][4][5]
