(a)
Interpretation: The given groups are to be ranked in the order of decreasing priority.
Concept introduction: A carbon atom that has four nonequivalent atoms or groups attached to it is known as chiral carbon atom. Chiral carbon centers are also called as asymmetric or stereogenic centers.
The priorities of the atoms that are directly attached to the stereogenic center are assigned in the order of decreasing
Answer to Problem 5.45P
The decreasing order of priority is
Explanation of Solution
The priority can be assigned by numbering the groups which are bonded to the chiral carbon atom based on the molecular weight and electronegativity.

The decreasing order of priority for the given groups is
Explanation of Solution
The priority can be assigned by numbering the groups which are bonded to the chiral carbon atom based on the molecular weight and electronegativity.
An atom of highest atomic number gets highest priority. Therefore, in the given groups,
For an atom which is a part of multiple bonds, the priority is assigned by treating the number of multiple bonded atoms equivalent to the number of singly bonded atoms. Among,
