1. Constitutional isomers, because constitutional isomers are those in which the ardangdnent of bonds are different it could be arranved in 3-D space.
2. They are the non superimposable mirror image to each other therefore Enantiomers.
3. Constitutional isomers, because the spatial arrangement of bonds are different.
4. By the rotation of some angles they will superimpose each other therefore identicals.
5. Identical molecules just different arrangement.
6. Diastereomers, because they aren't mirror image of each other.
