Question
**Task**: Rank the compounds in order of decreasing reactivity towards electrophilic aromatic substitution.

**Diagram Explanation**:
- The diagram features a large square box. The top of the box is labeled "Most reactive," and the bottom is labeled "Least reactive." This is a visual guide to help rank the reactivity of the given compounds.

**Answer Bank**:
- Three compounds are displayed at the bottom of the image, each as a chemical structure:
  1. Benzene ring with two carboxylic acid groups (HOOC and COOH) attached at the meta position.
  2. Benzene ring with two methyl groups (CH₃) attached at the ortho position.
  3. Benzene ring with a methyl group (CH₃) and a carboxylic acid group (COOH) attached at the meta position.

To complete the exercise, arrange these compounds within the provided box according to their reactivity towards electrophilic aromatic substitution, from most reactive to least reactive.

Expert Solution
Step 1: Explanation

Electron donating group (EDG) on benzene ring increases its reactivity towards electrophilic aromatic substitution and electron withdrawing group (EWG) decreases it's reactivity.

CH3 is an electron donating group (EDG)

COOH is an electron withdrawing group (EWG)
