Are the following pair(s) of structures resonance contributors or different compounds ? (U5e)

structure

Options:

Answer:
A
Solution:

The first cation is allylic (CH₃-CH⁺-CH=CH-CH₃). In the second the + sits on a CH₂ that is separated from the C=C by another CH₂ group, so the two differ in the positions of H atoms and the second is not allylic. They are different compounds.
