Fischer's projection formula
WebFischer projection, method of representing the three-dimensional structures of molecules on a page, devised by Emil Fischer. By convention, horizontal lines represent bonds projecting from the plane of the paper toward the viewer, and vertical lines represent bonds projecting away from the viewer. Fischer projections are a convenient way to depict … WebA Fischer projection of (2R,3S)−2,3−butanediol is : A B C D Medium Solution Verified by Toppr Correct option is A) 2R, 3S- 2, 3- butanediol ⇒ The compound is optically inactive even though it has 2 chiral carbons because of 2R and 3S. So, the structure should be symmetry in order to be optically inactive. ⇒ They are symmetric.

WebJul 20, 2024 · In a Fischer projection, the carbon atoms of a sugar molecule are connected vertically by solid lines, while carbon-oxygen and carbon-hydrogen bonds are shown horizontally. Stereochemical information is conveyed by a simple rule: vertical bonds point into the plane of the page, while horizontal bonds point out of the page. WebFischer projection, method of representing the three-dimensional structures of molecules on a page, devised by Emil Fischer. By convention, horizontal lines represent bonds …
WebDrawing Fischer Projections of Chiral Molecules 6 To generate the Fischer projection of a chiral molecule: (i) Identify the longest carbon chain that passes through all the chiral centres. (ii) Rotate the zigzag structure 90o on the plane so that the most oxidized carbon connected to the chiral centre(s) is vertically-oriented at the top of the ... WebFischer projections are just another way of drawing compounds contacting chirality centers.
