Chapter 5, Problem 5.15P

(a)

Interpretation Introduction

Interpretation:

Increasing order of priority of the given groups has to be given. Given groups are $-C{H}_3,-H,-Br,-C{H}_{2}C{H}_3$

Concept Introduction:

The group attached to asymmetric center should be ranked based on the atomic number of atom which directly connected to asymmetric center. The higher the atomic number of atom, higher the priority. If there is tie, then consider the next atoms attached to the connected atom and so on.

(b)

Interpretation Introduction

Interpretation:

Increasing order of priority of the given groups has to be given. Given groups are $-OC{H}_3,-CH{\left(C{H}_3\right)}_2,-B\left(C{H}_{2}C{H}_3\right),-H$

Concept Introduction:

The group attached to asymmetric center should be ranked based on the atomic number of atom which directly connected to asymmetric center. The higher the atomic number of atom, higher the priority. If there is tie, then consider the next atoms attached to the connected atom and so on.

(b)

Interpretation Introduction

Interpretation:

Increasing order of priority of the given groups has to be given. Given groups are $-C{H}_3,-C{H}_{2}OH,-C{H}_{2}N{H}_2,-C{H}_{2}Br$

Concept Introduction:

The group attached to asymmetric center should be ranked based on the atomic number of atom which directly connected to asymmetric center. The higher the atomic number of atom, higher the priority. If there is tie, then consider the next atoms attached to the connected atom and so on.
