Question
**Question 15 of 32** **Instructions:** A common alkyne starting material is shown below. Predict the major product for each reaction. Ignore any inorganic byproducts. **Reactions and Prompts:** 1. **Left Pathway:** - **Reagents:** Cl₂ (1 equiv) - **Action:** Select to draw the product. 2. **Right Pathway:** - **Reagents:** 1. NaNH₂ 2. CH₃CH₂CH₂CH₂Br - **Action:** Select to draw the product. 3. **Bottom Left Pathway:** - **Reagents:** 1. BH₃-THF 2. H₂O₂, NaOH - **Action:** Select to draw the product. 4. **Bottom Right Pathway:** - **Reagents:** HCl (excess) - **Action:** Select to draw the product. **Diagrams:** - The central structure is a simple alkyne with two terminal groups (a triple bond carbon structure). - Arrows indicate the direction of the chemical reactions leading to different products based on the reagents used.

The image depicts a flowchart representing a series of organic chemistry reactions, likely intended as an instructional tool for educational purposes. Here's a detailed transcription and description: --- **Flowchart Breakdown:** - **Initial Structure:** - At the center, there is a chemical structure of an alkyne. - **First Reaction Pathway:** - **Reagent:** \( \text{Cl}_2 (1 \text{ equiv}) \) - **Product Box:** Leads to a box labeled "Select to Draw." - **Second Reaction Pathway:** - **Reagents:** 1. \( \text{NaNH}_2 \) 2. \( \text{CH}_3\text{CH}_2\text{CH}_2\text{CH}_2\text{Br} \) - **Product Box:** Leads to a box labeled "Select to Draw." - **Intermediate Structure:** - The alkyne structure is present between the initial and subsequent reactions. - **Third Reaction Pathway:** - **Reagents:** 1. \( \text{BH}_3\text{-THF} \) 2. \( \text{H}_2\text{O}_2, \text{NaOH} \) - **Product Box:** Leads to a box labeled "Select to Draw." - **Fourth Reaction Pathway:** - **Reagent:** \( \text{HCl} (\text{excess}) \) - **Product Box:** Leads to a box labeled "Select to Draw." --- The "Select to Draw" boxes signify areas where students or learners might be expected to draw the resulting structures or products from the given reactions. This instructional method encourages learners to actively engage in predicting and understanding reaction mechanisms and outcomes.
