- what should be the structures of F and G in the given reaction map in the photo?Draw the meso form of this compound. Use the wedge/hash bond tools to indicate stereochemistry where it exists. Show stereochemistry in a meso compound.What is the maximum number of stereoisomers possible for the attached compound?
- Stereochemistry in biological molecules is often denoted by the D‑ and L‑ convention, instead of the ?‑ and ?‑ configurations determined by the Cahn–Ingold–Prelog methodology. Naturally occurring α‑amino acids are typically in the L‑configuration. The Fischer projection of L‑alanine is shown. L‑alanine Identify which structures are equivalent to the L‑configuration.Draw the most stable confirmation of CLCH2CH2CH2CH2CL in dash wedge representationConvert the following chair conformation of the sugar beta-D-galactose into a structure that shows all the cis & trans relationships as hashed (down) and wedge (up) bonds. Use the wedge/hash bond tools to indicate stereochemistry where it exists. In cases where there is more than one answer, just draw one. Use “flat” representations of rings, not chairs, in your drawing.
- Stereochemistry in biological molecules is often denoted by the D‑ and L‑ convention, instead of the ?‑R‑ and ?‑S‑ configurations determined by the Cahn–Ingold–Prelog methodology. Historically, the glyceraldehyde enantiomer that rotated plane polarized light clockwise was arbitrarily designated as D and the other enantiomer was designated as the L configuration. The D‑glyceraldehyde Fischer projection is shown. D‑glyceraldehydeWhich group in the following pair is assigned the higher priority in R,Snomenclature −CD3, −CH3On the left is a stereorepresentation of glucose Q.Convert the stereorepresentation on the left to a chair conformation.
