3-Methylhexane is a branched hydrocarbon with two enantiomers. [2] It is one of the isomers of heptane. The molecule is chiral, and is one of the two isomers of heptane to have this property, the other being its structural isomer 2,3-dimethylpentane. The enantiomers are (R)-3-methylhexane [3] and (S)-3-methylhexane. [4]
The longest possible main alkane chain is used; therefore 3-ethyl-4-methylhexane instead of 2,3-diethylpentane, even though these describe equivalent structures. The di-, tri- etc. prefixes are ignored for the purpose of alphabetical ordering of side chains (e.g. 3-ethyl-2,4-dimethylpentane, not 2,4-dimethyl-3-ethylpentane).
2-Methylhexane (C 7 H 16, also known as isoheptane, ethylisobutylmethane) is an isomer of heptane. It is structurally a hexane molecule with a methyl group attached to its second carbon atom.

Ethylvanillin can be methylate to 4-ethoxy-3-methoxybenzladehyde. The 4-ethoxy-3-methoxybenzaldehyde is then subjected to a Bayer-Villiger oxidation with peracetic acid and acetic acid to yield 4-ethoxy-3-methoxyphenol. The 4-ethoxy-3-methoxyphenol is methylated to yield 2,4-dimethoxy-1-ethoxybenzene. The 2,4-dimethoxy-1-ethoxybenzene is ...
