  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. A Newman projection visualizes the conformation of a chemical bond from front to back, with

  3. C2H3Br3 - Wikipedia

    en.wikipedia.org/wiki/C2H3Br3

    The molecular formula C 2 H 3 Br 3 (molar mass: 266.76 g/mol, exact mass: 263.7785 u) may refer to: Tribromoethanes. 1,1,1-Tribromoethane; 1,1,2-Tribromoethane

  4. Tetrabromoethane - Wikipedia

    en.wikipedia.org/wiki/Tetrabromoethane

    1,1,2,2-Tetrabromoethane, or simply tetrabromoethane (TBE), is a halogenated hydrocarbon, chemical formula C 2 H 2 Br 4.Although three bromine atoms may bind to one of the carbon atoms creating 1,1,1,2-tetrabromoethane this is not thermodynamically favorable, so in practice tetrabromoethane is equal to 1,1,2,2-tetrabromoethane, where each carbon atom binds two bromine atoms.

  5. 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. Stereochemistry - Wikipedia

    en.wikipedia.org/wiki/Stereochemistry

    Stereochemistry, a subdiscipline of chemistry, studies the spatial arrangement of atoms that form the structure of molecules and their manipulation. [1] The study of stereochemistry focuses on the relationships between stereoisomers, which are defined as having the same molecular formula and sequence of bonded atoms (constitution) but differing in the geometric positioning of the atoms in space.

  7. Staggered conformation - Wikipedia

    en.wikipedia.org/wiki/Staggered_conformation

    Staggered conformation image right in Newman projection Eclipsed conformation. In organic chemistry, a staggered conformation is a chemical conformation of an ethane-like moiety abcX–Ydef in which the substituents a, b, and c are at the maximum distance from d, e, and f; this requires the torsion angles to be 60°. [1]
