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 boiling point of 89.7 °C is 0.3 °C higher than the value of 89.4 °C predicted by Wiener's formula, based on the structure of the molecule and the boiling point of n-heptane. [2] [3] The speed of sound at 3 MHz is 1149.5 m/s at 20 °C and 889.5 m/s at 80 °C. [7] [8] [9]

3D structure A Newman projection is a drawing that helps visualize the 3-dimensional structure of a molecule. [ 1 ] This projection most commonly sights down a carbon-carbon bond, making it a very useful way to visualize the stereochemistry of alkanes.

Thus, the name is 3-methylpentane to avoid ambiguity: The 3- is because the methyl is attached to the third of the five carbon atoms. If there is more than one of the same alkyl group attached to a chain, then the prefixes are used on the alkyl groups to indicate multiples (i.e., di, tri, tetra, etc.)
