Answer
a) resonance structures
b) neither
c) isomer
d) isomer
Work Step by Step
1) First, check if they are isomers by comparing their molecular formulas. If they do not have the same molecular formulas, then they cannot be isomers or resonance structures. However, if they have the same molecular formula, proceed to step 2.
2) Compare the two compounds and then take note of the difference in the placement of atoms or electrons.
3) If the two compounds differ only in the arrangement of electrons, then they are resonance structures. However, if they differ in the arrangement of both atoms and electrons, then they are isomers.
