Chapter 22.1, Problem 3PP

Interpretation Introduction

Interpretation:

The name of the given aryl halide needs to be determined.

Concept introduction:

The aryl halides are named after determining the halide group present in it. Generally in organic compounds, on the benzene substitution of different groups result in the formation of different compounds. The carbon atoms in the ring are numbered first and then the sides groups are identified. The naming of the side groups is done by following the alphabetical order.

Answer to Problem 3PP

1, 3-dibromo-2-chlorobenzene.

Explanation of Solution

The given organic compound is as follows:

There are 2 bromide groups and 1 chloride group on the benzene ring. If naming is done alphabetical order of the halide groups, it will be represented as follows:

Thus, bromide group is at 1^st and 3^rd positions and chloride group is at 2^nd position.

Therefore, the name of the compound will be 1, 3-dibromo-2-chlorobenzene.

Conclusion

Thus, the name of the given compound is 1, 3-dibromo-2-chlorobenzene.
