Explanation:

1. For the first pair: Isomers have the same molecular formula but different structures. Resonance structures are different Lewis - structures that contribute to the overall structure of a molecule. The first two structures have different arrangements of atoms and bonds and are not resonance structures (as resonance involves only movement of electrons, not atoms). So they are isomers.
2. For the second pair: The two structures have different connectivity of atoms and are not resonance structures (no electron - only movement to convert one to the other). So they are isomers.
3. For the third pair: These structures are resonance structures as they are different Lewis - structures of the same molecule with the same overall connectivity and only the position of electrons is different.

Answer:

1. isomers
2. isomers
3. resonance structures
