In 1929 Graham Edgar and George Calingaert made 3,3-dimethylpentane and measured its physical characteristics for the first time. The measurements were at 20 °C, not the standard conditions used in later times. [3] For 3,3-dimethylpentane they measured a density of 0.6934 at 20 °C with a rate of change Δd/ΔT of 0.000848.
The optical center is the middle carbon of the pentane backbone, which is connected to one hydrogen atom, one methyl group, one ethyl group – C 2 H 5, and one isopropyl group – CH(CH 3) 2. The two enantiomers are denoted (3R)-2,3-dimethylpentane and (3S)-2,3-dimethylpentane (the other simplest chiral alkane is its structural isomer 3 ...

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]
Its measure of prices paid by manufacturers dropped to 50.3 from 54.8 in October, suggesting goods prices have room to fall, though higher tariffs could see a reversal.
