The following groups are ortho$-$para directors. Draw a contributing structure for the resonance$-$stabilized cation formed during electrophilic aromatic substitution that shows the The following groups are ortho$-$para directors. Draw a contributing structure for the resonance$-$stabilized cation formed during electrophilic aromatic substitution that shows the

role of each group in stabilizing the intermediate by further delocalizing its positive charge. $($The positive charge should not reside on the substituted ring.$)$

Hydrogen atoms not attached to carbon atoms.

Apply formal charges where appropriate.

Assign lone pairs and radical electrons where appropriate.
