Question
**Extraction Flowchart Exercise** **Objective:** Create an extraction flowchart to separate the following compounds: 1. Aniline (Ph-NH₂) 2. Benzoic acid (Ph-CO₂H) 3. Ethyl benzene (Ph-CH₂CH₃) **Instructions:** Use Figure 3-8 as a guide to complete your flowchart design. In this task, you will apply your knowledge of organic chemistry separation techniques to effectively isolate each compound from a mixture. Consider the chemical properties and reactivity of each compound when designing your flowchart.

**Title: Understanding Acid-Base Extraction through a Flowchart** This image presents a detailed flowchart illustrating the process of acid-base extraction for separating different organic compounds using ether as a solvent. Let's break down the steps and components involved in this process: 1. **Starting Compounds**: - The initial mixture consists of HA (an organic acid), B (an organic base), and N (a neutral compound) dissolved in ether. 2. **Addition of NaOH(aq)**: - The process begins by adding aqueous sodium hydroxide (NaOH) to the mixture. - This causes the organic acid (HA) to form its sodium salt (Na⁺ A⁻) in water, separating it from the ether layer. 3. **Pathway for HA**: - The aqueous layer containing Na⁺ A⁻ is acidified using hydrochloric acid (HCl) and combined with ether. - The result is the extraction of HA back into the ether layer. Evaporation of ether yields pure HA. 4. **Compounds B and N (in ether)**: - These remain in the ether layer after the NaOH treatment. - To separate them, aqueous hydrochloric acid (HCl) is added. 5. **Pathway for B (Organic Base)**: - The addition of HCl leads to the formation of HB⁺ Cl⁻ in the water layer. - By basifying this layer with NaOH and adding ether, B is re-extracted into the ether layer. - Evaporation of ether provides pure B. 6. **Pathway for N (Neutral Compound)**: - The neutral compound N stays in the ether layer throughout the HCl treatment. - Simple evaporation of ether from this layer yields pure N. **Conclusion:** This flowchart effectively summarizes the methodical steps required in an acid-base extraction to isolate individual components from a mixed organic solution. It highlights how the use of appropriate acid or base, coupled with solvent partitioning, leads to selective extraction and purification of compounds. This technique is widely used in organic chemistry for separating components based on their distinct acidic, basic, or neutral properties. **Figure legend**: - **FIGURE 3-8**: Extraction flowchart in acid-base extraction.
