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 page provides a comprehensive list of isomers of dodecane, including their chemical structures and properties.
Heptanone may refer to the following ketones with seven carbon atoms the formula C 7 H 14 O: . 2-Heptanone (Methyl amyl ketone) . 5-Methyl-2-hexanone (Methyl isoamyl ketone); 4-Methyl-2-hexanone (Methyl 2-methylbutyl ketone)
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 ...
3-Ethylpentane (C 7 H 16) is a branched saturated hydrocarbon. It is an alkane, and one of the many structural isomers of heptane, consisting of a five carbon chain with a two carbon branch at the middle carbon. An example of an alcohol derived from 3-ethylpentane is the tertiary alcohol 3-ethylpentan-3-ol. [3]
The resulting product, diethyl 3,5-dimethylpyrrole-2,4-dicarboxylate, has been called Knorr's Pyrrole ever since. In the Scheme above, R 2 = COOEt, and R 1 = R 3 = Me represent this original reaction. Knorr's pyrrole can be derivatized in a number of useful manners. One equivalent of sodium hydroxide will saponify the 2-ester selectively.
