WebDraw the Fischer projection formulas of the isomeric d-3-ketopentoses. Answer: There are two equivalent stereogenic centers in a 3-ketopentose. An enantiomeric pair of compounds and a meso compound are possible. The first structure, (a), has the d configuration. The second, (b), is its enantiomer, and has the l configuration. WebJul 5, 2024 · In 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). beau bertke

Fischer Projections Explained: The features of this projection consist … Chiral molecules can be described as ones with a set of stereoisomers or left and right-handed enantiomers. As defined by Lord Kelvin, a molecule has chirality “if its image in a plane mirror, ideally realized, cannot be brought to coincide with itself.” In other words, a chiral molecule is asymmetrical in the sense that it's mirror image will not be an exact copy of itself. Chirality is key to understand in many fields such as drug development as one enantiomer of a drug may caus… beau berlinWebFischer projections are used frequently in organic chemistry.
