Interpretation:
The compounds having delocalized electrons have to be predicted.
Concept Introduction:
Resonance Contributor: The appropriate structure with the delocalized electrons is called a resonance contributor, a resonance structure, or a contributing resonance structure.
Delocalized electrons: The sharing of electrons between two or more atoms known as delocalization of electrons. In order to have delocalized electrons, the system must be planar and have alternative double bonds and single bonds.
Resonance hybrid: The actual structure with delocalized electrons is called a resonance hybrid.
Explanation of Solution
Reason for correct options:
The above compounds all have delocalized electrons, which undergo electron movement.
The resonance structures can be drawn as shown above.
Hence, the correct options are A, B, C, E, J, K and L.
Reason for in-correct options:
The remaining compounds do not contain delocalized electrons since the conjugated system is absent.
Hence, the in-correct options are D, F, G, H, I, J, and K.
The compounds containing delocalized electrons were predicted.
