WebThe Newman projections show that propane has a set of eclipsed and staggered conformations similar to ethane, but with a torsional strain of 3.3 kcal/mol. Each eclipsed conformation now consists of two eclipsed C-H … WebIn a Newman projection, the “substituents” of each atom composing the bond, be they hydrogens or functional groups, can then be viewed both in front of and behind the carbon-carbon bond. Specifically, one can observe the angle between a substituent on the front atom and a substituent on the back atom in the Newman projection, which is ...

Web22 feb. 2024 · Newman projections. In a Newman projection, we are looking down a carbon-carbon bond axis so that the two atoms are one-behind-the-other. In the Newman projection of propane (below), C-1 is the blue methyl group, C-2 is at the centre of the circle, and C-3 is hidden directly behind it. WebNewman Projections. Newman projections are drawn by looking directly along a particular bond in the system (here a C-C bond) and arranging the substituents so that they are equally spaced around the atoms at each end of that bond.

WebThe Newman projection is obtained upon a 90° degree rotation of the dash-wedge structure. It is an end-on representation where the molecule is viewed along the bond of interest, a projected bond. The atom farther from the observer is represented by a circle, and the atom closer to the observer is denoted as the center of the circle.
