What are the isomers of chlorobromobenzene

To determine the isomers of chlorobromobenzene, we need to consider the different possible arrangements of the chlorine (Cl) and bromine (Br) atoms on the benzene ring.
The benzene ring consists of six carbon atoms bonded together in a hexagonal shape. We can number the carbon atoms from 1 to 6 for reference. In chlorobromobenzene, both chlorine and bromine atoms replace hydrogen atoms attached to carbon atoms on the benzene ring.
There are three possible isomers of chlorobromobenzene:
1. Ortho-isomer: In this isomer, the chlorine and bromine atoms are located on adjacent carbon atoms on the benzene ring (ortho- position). The possible numbering of the carbon atoms is 1 and 2 or 2 and 3.
Possible structures:
Cl Cl

1-C-2 or 2-C-3
/ \
Br Br
2. Meta-isomer: In this isomer, the chlorine and bromine atoms are located on carbon atoms that are separated by one carbon atom on the benzene ring (meta- position). The possible numbering of the carbon atoms is 1 and 3 or 2 and 4.
Cl Cl

1-C-3 or 2-C-4
/ \
Br Br
3. Para-isomer: In this isomer, the chlorine and bromine atoms are located on carbon atoms that are opposite to each other on the benzene ring (para- position). The possible numbering of the carbon atoms is 1 and 4 or 2 and 5.
Cl Cl

1-C-4 or 2-C-5

Br Br
Remember that isomers have the same molecular formula (in this case C6H4ClBr), but different connectivity or spatial arrangements of atoms.
