Question
**Title: Understanding Reduction Reactions in Multistep Syntheses**

During multistep syntheses, reduction reactions are often performed. Functional groups react differently with these reagents. With this in mind, you are tasked with drawing the structure of the product of this reaction:

**Chemical Reaction:**

- **Starting Material:** The structure is an aromatic compound with multiple carboxyl and carbonyl groups. It includes:
  - Three carboxylic acid groups (CO₂H).
  - One ketone group (C=O) fused into the ring system.

- **Reagent Used:** Lithium aluminum hydride (LiAlH₄) is indicated as the reagent for reduction.

**Instructions:**

- Draw the structure of the product after the reaction with LiAlH₄, considering selective reduction of functional groups.

**Sketchpad Interface:**

- The starting material is displayed in the sketchpad.
- The sketchpad tools include various functional icons such as drawing bonds, rings, atoms, and tools for navigating or modifying the structure.

**Diagram Description:**

- The displayed structure in the sketchpad is identical to the initial structure shown above with carboxylic acid and ketone groups apparent in the aromatic ring system.

**Educational Note:**

Understanding the reactivity and transformation of functional groups like carboxylic acids and ketones with strong reducing agents such as LiAlH₄ is crucial for successfully executing and interpreting multistep synthetic pathways.
