### Chemical Reactivity and Stability QuizThis section explores various chemical structures to understand their reactivity and stability properties. Four questions are presented to test your knowledge on these topics, accompanied by diagrams of chemical compounds.#### Questions:**a) Which structure is more reactive toward electrophilic aromatic substitution (EAS reaction)?****b) Which structure is more acidic?****c) Which substrate is more reactive toward nucleophilic substitution reaction?****d) Which carbocation is more stable?**#### Diagrams and Choices:**a) Electrophilic Aromatic Substitution (EAS) Reactivity**- **Structure A:** Benzene ring with a methyl group.- **Structure B:** Benzene ring with a nitro group.**b) Acidity**- **Structure C:** Benzene ring with a methoxy group and a hydroxyl group.- **Structure D:** Benzene ring with a nitro group and a hydroxyl group.**c) Nucleophilic Substitution Reactivity**- **Structure E:** Ethyl acetate (ester group).- **Structure F:** Acetyl chloride (acyl chloride group).**d) Carbocation Stability**- **Structure G:** Isopropyl carbocation.- **Structure H:** Tert-butyl carbocation.#### Explanation of Diagrams:Each question includes structures for comparison, labeled A through H. For each question, identify the structure that corresponds to the answer by selecting the more reactive or stable species.1. **EAS Reactivity:** - Structure B with a nitro group usually deactivates the ring, decreasing EAS reactivity. Structure A with a methyl group is an activating group, increasing reactivity. 2. **Acidity:** - Structure D with a nitro group will typically be more acidic compared to structure C with a methoxy group because the nitro group is an electron-withdrawing group, stabilizing the negative charge on the conjugate base.3. **Nucleophilic Substitution:** - Structure F (acetyl chloride) is more reactive toward nucleophiles than structure E (ethyl acetate) due to the better leaving ability of the chloride ion.4. **Carbocation Stability:** - Structure H (tert-butyl carbocation) is more stable than structure G (isopropyl carbocation) because tertiary carbocations are more stabilized by hyperconjugation and inductive effects than
