Concept explainers
(a)
Interpretation:
From the given compounds, compounds having delocalised electrons have to be identified.
Concept Introduction:
Delocalized electrons: Electrons that are not localized in one particular atom or bond and shared by three or more atoms are called delocalized electrons.
Resonance contributor: In some chemical compounds like benzene pi electrons are delocalized in it and difficult to locate it. Resonance contributor gives an idea of where about of pi electrons. The exact structure with localized electrons are called resonance contributor.
