Interpretation:
The absolute configuration
Concept introduction:
A chirality center is the tetrahedral carbon which is directly attached to four different atoms or groups.
In the Fischer projection, the vertical bonds point away from the observer while the horizontal bonds point towards the observer.
When determining the configuration, the molecule is oriented such that the lowest ranked atom points away from the observer.
The order of decreasing priorities of the three other atoms or groups is decided. If it traces a clockwise path, the configuration is R and if it traces a counterclockwise path, the configuration is S.
