Question

Please help, I thought bromide would be removed first and I am confused. 

**Problem 3:**

Please provide a plausible mechanism for the following transformation. Include any and all lone pairs and formal charges in addition to all required reaction arrows and intermediates.

**Reaction:**

- **Reactants:**
  - A bromobenzene ring with a nitro group (NO₂) at the ortho position relative to a bromine atom (Br) is shown.
  - Sodium amide (Na⁺NH₂⁻) is the reagent.

- **Products:**
  - An aniline derivative with the nitro group (NO₂) at the ortho position relative to an amino group (NH₂), which has replaced the bromine atom.

**Description:**

In this reaction, the bromine atom on the benzene ring is substituted by an amino group (NH₂), resulting in the formation of an ortho-nitroaniline. The reaction likely involves nucleophilic aromatic substitution.

**Instructions:**

Provide a detailed mechanism that includes:
- Identification of lone pairs and formal charges.
- All necessary reaction arrows illustrating the step-by-step process.
- Any intermediate structures formed during the reaction.
