Answer :

The no. Of possible isomers for bromo-chloro benzene is 3.

Three possible isomers for bromo-chloro benzene is 1-bromo-2-chlorobenzene, 1-bromo-3-chlorobenzene & 1-bromo-4-chlorobenzene.

Isomers are identical molecules with different structural characteristics. As a result, although having the same number of atoms in each element, isomers have different atomic arrangements.

Even if all molecules have the same molecular formula, they may have various physical characteristics, especially if their respective functional groups are unique. Isomerization is the transformation of one molecule into another molecule with the same number of atoms. This could happen on its own or maybe a reaction is needed to make it happen.

Isomers are generally divided into two categories:-

  • Structural isomerism - have same molecular formula but different structural formula.
  • Stereo isomerism - Have same molecular formula but different arrangement of atoms in 3d space.
