Concept explainers
a)
Interpretation:
Each drawing given in the problem is to be oriented so that the lowest ranked group is towards the rear and the configuration as R or S is to be assigned.
Concept introduction:
The groups attached to a chiral carbon are ranked based on the sequence rules. The molecule is oriented in such a way that the group of lowest ranking points directly away from the viewer. If a curved arrow drawn from the highest to second highest to third highest ranked substituent is clockwise, the chirality centre is assigned R configuration. If the arrow is anticlockwise it is assigned s configuration.
To orient:
Each drawing given in the problem so that the lowest ranked group is towards the rear and to assign the configuration as R or S.
