Question: Use the curved arrow formalism to show how the electrons flow in the resonance form on the left to give the one on the right.

a)

b)

c)

Resonance is nothing but the delocalization of electrons within a molecule.

There are certain rules to draw the resonating structure:

In the following resonating structure lone pair of electrons on nitrogen is delocalize which results in the formation following structure;

Resonance is nothing but the delocalization of electrons within a molecule.

There are certain rules to draw the resonating structure:

In the following resonating structure lone pair of electrons on oxygen is delocalized, which results in the formation following structure;

Resonance is nothing but the delocalization of electrons within a molecule.

There are certain rules to draw the resonating structure:

In the following resonating structure of benzene, $\mathrm{\pi }$electrons are delocalized, which results in the formation following structure;
