Question
Help please. Draw the curved arrow notation and products for the each elementary step described by the sequence shown here.
Note that the products of each step should be used as the reactants in the next step, and you may need to draw in additional reagents as directed. Remember to click on each box to see step-specific instructions.
Draw H3CH2C–, and then add the curved arrow notation showing a nucleophilic addition.

Transcribed Image Text:## Organic Chemistry Mechanism Exercise
**Instructions:** Be sure to include all lone pair electrons and nonzero formal charges in your diagram.
### Reaction Mechanism Steps
1. **Step 1:** Analyze the given structural formula (displayed as a starting point) and determine the initial interactions that will take place.
2. **Step 2:** Fill in the next box with the intermediate formed after the first chemical interaction, including all lone pair electrons and formal charges.
3. **Step 3:** Continue the reaction by identifying the next chemical transformation, filling the third box accordingly.
4. **Step 4:** Draw the final product in the last box, showcasing the complete reaction sequence.
### Structure and Notation Task
- **Objective:** Draw the structure H₃CCH₂C⁻.
- **Task:** Add the curved arrow notation to show a nucleophilic addition to the given substrate. Use the drawing tool provided to construct the molecule and depict the electron flow accurately.
### Drawing Tool
- A tool interface is provided for constructing and editing chemical structures. Use the tool palette to select appropriate elements and bonds to accurately depict the molecules and reactions.

Transcribed Image Text:**Instructions for Curved Arrow Notation and Reaction Sequence**
1. **First Step: Nucleophilic Addition Involving \( \text{H}_3\text{CH}_2\text{C}^- \)**
- Begin by performing a nucleophilic addition where the nucleophile is the anion \( \text{H}_3\text{CH}_2\text{C}^- \).
2. **Second Step: Nucleophile Elimination**
- Follow the first step with a nucleophile elimination process. This step involves removing a nucleophile from the reactant.
3. **Third Step: Nucleophilic Addition Involving \( \text{H}_3\text{CH}_2\text{C}^- \)**
- Conduct another nucleophilic addition, using the same nucleophile \( \text{H}_3\text{CH}_2\text{C}^- \) as in the first step.
4. **Fourth Step: Proton Transfer Involving \( \text{H}_3\text{O} \)**
- End the sequence with a proton transfer, involving \( \text{H}_3\text{O} \).
**Notes:**
- Ensure that the products from each step are used as the reactants in the subsequent step.
- Additional reagents may need to be added where specified.
- Refer to individual instructions provided for each step in the boxes.
**Diagram Explanation:**
- The diagram illustrates an organic molecule featuring a 4-carbon chain connected to an ester functional group (\( \text{O=COC} \)).
- Curved arrow notations should reflect the movement of electrons during these transformations.
