Chemistry projections
WebFischer projections were originally developed by German chemist Emil Fischer for work on carbohydrate (sugar) chemistry. It's a way to quickly draw multiple sugars and compare them since it's easy to spot the asymmetric carbons on a Fischer projection.

WebDec 15, 2024 · Chair conformation of cyclohexane. Cyclohexane is the most stable cycloalkane. It is strain-free, meaning neither angle strains nor torsional strains apply, and it shows the same stability as chain alkanes. This special stability is due to a unique conformation that it adopts. The most stable conformation of cyclohexane is called “ chair ... WebIn a Fischer projection drawing, the four bonds to a chiral carbon make a cross with the carbon atom at the intersection of the horizontal and vertical lines. The two horizontal bonds are directed toward the viewer (forward of the stereogenic carbon). The two vertical bonds are directed behind the central carbon (away from the viewer).

WebMay 12, 2024 · It is defined as the angle between any two atoms attached to neighboring carbons in the Newman projection. For example, the two methyl groups above (in red) are attached to neighboring carbons. The angle between the two as seen in the Newman projection is zero (that is, they overlap, or” eclipse” each other).
