SUMMARY

The discussion centers on determining the R/S configuration of stereochemical compounds using Fischer Projections. The user confirms that for accurate representation, hydrogen must be oriented away from the viewer, which aligns with the standard conventions of stereochemistry. The manipulation of the molecule to achieve this orientation is essential for correct configuration assignment. The user seeks validation on their understanding and representation of the Fischer Projection.

PREREQUISITES
  • Understanding of stereochemistry concepts, specifically R/S configuration.
  • Familiarity with Fischer Projections and their conventions.
  • Knowledge of molecular manipulation techniques to visualize stereochemical arrangements.
  • Basic grasp of organic chemistry principles related to chirality.
NEXT STEPS
  • Study the conventions of Fischer Projections in detail.
  • Learn about the Cahn-Ingold-Prelog priority rules for R/S configuration determination.
  • Explore stereochemical representations in 3D using molecular modeling software.
  • Review examples of stereochemical problems to practice configuration assignments.
USEFUL FOR

Chemistry students, organic chemists, and anyone involved in stereochemical analysis and molecular representation will benefit from this discussion.

Stereochemistry, PLZ HELP!

ok far left is the original problem

i manipulated it so that hydrogen and cyanide is facing me, but in order to determine R/S configuration. hydrogen must be going away from me, correct? so i flipped it so that it is not going away from me, and i determined it to be S.

but on paper, for correct representation of a Fischer Projection, i would draw the one that has my horizontal plane coming towards me, correct? (the one circled)

please confirm this for me! any advice is appreciated.
