Concept explainers
Which of the following structures are identical? (Green = Cl.)

Interpretation:
Among the four structures given which are identical is to be stated.
Concept introduction:
All the four structures given have chiral carbons. By assigning the configuration as R or S the identical structures can be identified.
To state:
Which among the four structures given are identical.
Answer to Problem 26VC
Structures a, b, and d are identical. Structure c is different.
Explanation of Solution
The chiral carbon in all the four structures given is attached to the same four groups, H, Cl, CH3 and COOH but differently oriented. When the sequence rules are applied to these four groups, the order of priority obtained is Cl, COOH, CH3 and H. Using this priorities the configuration of the four structures can be obtained. It is clear that a, b and d have R configuration and d has S configuration. Hence a, b and d represent identical structures and c represents a different configuration.
Structure a, b, and d are identical. Structure c is different.
