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.
Figure 5 shows 2-chloro-2,3-dimethylbutane in a sawhorse projection with chlorine and a hydrogen anti-periplanar to each other. Syn-periplanar or synperiplanar is similar to anti-periplanar. In the syn-periplanar conformer, the A and D are on the same side of the plane of the bond, with the dihedral angle of A−B and C−D between +30° and ...
Melvin Spencer Newman (March 10, 1908 – May 30, 1993) was an American chemist, Ohio State University professor, best known for inventing the Newman projection. Newman was born in New York City in a Jewish family, the youngest of Mae (née Polack) and Jacob K. Newman's four children. [ 1 ]
The skeletal formula of the antidepressant drug escitalopram, featuring skeletal representations of heteroatoms, a triple bond, phenyl groups and stereochemistry. The skeletal formula, line-angle formula, bond-line formula or shorthand formula of an organic compound is a type of molecular structural formula that serves as a shorthand representation of a molecule's bonding and some details of ...
sawhorse projection Free energy diagram of n -butane as a function of dihedral angle. In stereochemistry , a torsion angle is defined as a particular example of a dihedral angle, describing the geometric relation of two parts of a molecule joined by a chemical bond .
“I could have asked a store associate and gotten the same answer, but, you know, he was tall, and handsome,” she jokes. “I was like, ‘I’m gonna shoot my shot.’ So I did, and completely ...
In chemistry, the Natta projection (named for Italian chemist Giulio Natta) is a way to depict molecules with complete stereochemistry in two dimensions in a skeletal formula.
