**Question E: Ranking of Benzene Derivatives by Activation and Directive Properties**

**Objective:** Rank the following molecules in decreasing order of activation (from most activated, assigned a rank of 1, to most deactivated, assigned a rank of 6) based on the substituents present on the benzene ring. Also, indicate whether the substituents are ortho-para or meta directors.

**Molecules Provided:**

1. **Molecule A:** Benzoic acid (benzene ring with a carboxyl group, -COOH)
2. **Molecule B:** Isopropylbenzene (benzene ring with an isopropyl group, -CH(CH₃)₂)
3. **Molecule C:** Nitrobenzene (benzene ring with a nitro group, -NO₂)
4. **Molecule D:** Aniline (benzene ring with an amino group, -NH₂)
5. **Molecule E:** Chlorobenzene (benzene ring with a chloro group, -Cl)
6. **Molecule F:** Benzyl acetate (benzene ring with an acetoxy group, -OCOCH₃)

**Instructions for Ranking and Directive Properties:**
- **Activation trend:** The activation or deactivation of the benzene ring depends on the substituent’s electronic effects. Electron-donating groups (EDGs) activate the ring, whereas electron-withdrawing groups (EWGs) deactivate the ring.
- **Directive properties:** Substituents can be either ortho-para directors (EDGs usually) or meta directors (EWGs usually).

**Analyzed Details:**

1. **Aniline (-NH₂):**
   - **Activation:** Strong electron-donating group.
   - **Directive Property:** Ortho-para director.
   - **Rank:** 1 (most activated).

2. **Isopropylbenzene (-CH(CH₃)₂):**
   - **Activation:** Moderately electron-donating group.
   - **Directive Property:** Ortho-para director.
   - **Rank:** 2.

3. **Chlorobenzene (-Cl):**
   - **Activation:** Weakly deactivating group (due to inductive withdrawal but resonance donation).
   - **Directive Property:** Ortho-para director.
   - **Rank:** 3.

4. **Benzoic acid (-COOH):**
