3-Methylheptane is a branched alkane isomeric to octane. Its structural formula is CH 3 CH 2 CH(CH 3)CH 2 CH 2 CH 2 CH 3. It has one stereocenter. Its refractive index is 1.398 (20 °C, D). [citation needed]
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).
This is a free rotation only in the simplest cases like gaseous methyl chloride CH 3 Cl. In most molecules, the remainder R breaks the C ∞ symmetry of the R−C axis and creates a potential V(φ) that restricts the free motion of the three protons. For the model case of ethane CH 3 CH 3, this is discussed under the name ethane barrier. In ...
