Concept explainers
(a)
Interpretation:
The configuration for the given moleculehas to be assigned.
Concept Introduction:
Priority rules:
- Priorities based on
atomic number
- When priority cannot be assigned on the basis of the atoms bonded directly to the chiral center
- Atoms participating in a double or triple bond are considered to be bonded to an equivalent number of phantom atoms.
For example,
- Priority assignment is made at the first point of difference between groups (should not be based on the larger group).
(b)

The configuration for the given molecule has to be assigned.
