  2. Newman projection - Wikipedia

    en.wikipedia.org/wiki/Newman_projection

    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.

  3. Rotamer - Wikipedia

    en.wikipedia.org/wiki/Rotamer

    Above: Newman projection; below: depiction of spatial orientation. In chemistry, rotamers are chemical species that differ from one another primarily due to rotations about one or more single bonds. Various arrangements of atoms in a molecule that differ by rotation about single bonds can also be referred to as different conformations ...

  6. 3-Methylhexane - Wikipedia

    en.wikipedia.org/wiki/3-Methylhexane

    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 example below is looking down the C2 and C3 bond. Below is the sawhorse and Newman representation of butane in an eclipsed conformation with the two CH 3 groups (C1 and C4) at a 0-degree angle from one another (left). If the front is rotated 60° clockwise, the butane molecule is now in a staggered conformation (right).
