Question

3. Draw all possible resonance structures for aniline. Relate the resonance structures to why it is an ortho/para director. 3. Drawhy it is нони 19 Pa

Answer 1

The all possible resonance structures of Aniline are as follows by the below  image-

Steptat in thriline Resonance structures - : o Step all & loan and pair (..) shifts to make a bord the structure is: No loses its own election - ons) ro, it has a (tre) charge. Step 3 - 80, again loan pairs (-) shifted to the next and structure is:

Step 4 - : histed Again the Abond is breaked and the next for etnolleture - : to Step 5 – loom pair shifts to the next and T-bond getums to it's original state. Nh getback Jet's ē to lose it. and t. and the charge is escaped. NH₂

- Thas a combining all these structures as:
These are the all possible resonance diagrams .

since, ortho and para positions are more electron dense and thus, the electrophillic substitution takes place at ortho and para positions as you can see the above resonance structures. There is electron dense area , so it is the director at only ortho and para positions for the Aniline structure.
