# Which of the following statement is incorrect on resonance ?

$\begin{array}{1 1}(a)\;\text{Resonance leads to extra stability}\\(b)\; \text{Any number of resonance hybrid can be proposed}\\(c)\;\text{The actual structure a hybrid of the various extreme possibilities}\\(d)\;\text{Resonance hybrid is more stable than any one of the constituting structures}\end{array}$

Toolbox:
• When we can draw two (or more) forms of the same molecule that differ only in the placement of their electrons – is called resonance, and the different structures we draw are called resonance forms.
• Resonance structures are not real, they just show possible structures for a compound.
• The more resonance forms a molecule has makes the molecule more stable.
Any number of resonance hybrid can be proposed
Hence (b) is the correct answer.
