## Reaction Pathway to Synthesize 2-Methylhept-3-yne

**Objective:**
Draw the structures of the starting materials needed to make 2-methylhept-3-yne or 2-methyl-3-heptyne. The starting materials may be any bromoalkane having five carbons or fewer.

**Reaction Sequence:**

1. **Starting Material A**: It is a bromoalkane with five carbons or fewer.

2. **Reaction Steps**:
- **Intermediate B**: Formed by the reaction of Starting Material A with 2 equivalents of NaNH₂ in mineral oil, under heat.
- **Intermediate C**: Generated from Intermediate B by reacting with NaNH₂ in liquid NH₃, forming a sodium acetylide ion.
- **Final Product**: Obtained by reacting Intermediate C with reagent C to form 2-methylhept-3-yne.

**Instructions to Students:**

- **Draw Starting Material A**: Utilize a bromoalkane with five carbons or fewer.
- Options include drawing tools with single, double, and triple bonds, carbon, hydrogen, and bromine atoms.

- **Draw Reagent C**: Similar constraints apply as in Starting Material A, ensuring it is a bromoalkane with five carbons or fewer.

**Interactive Tools Description:**
- Provided drawing tools allow for detailed molecular depiction, including bond type selection and atom placement.
- Zoom and undo/redo functionalities facilitate precise and user-friendly design of molecular structures.

This exercise aids in understanding the synthesis of complex organic compounds starting from basic hydrocarbon units.

In lab we often start with clear liquids and end with clear liquids, so how to we know if we even did the experiment correctly? How do we know if we really made the product we "think" we made? In this lab the goal was to convert cyclohexanol to cyclohexene. Since the product is supposed to be an alkene, based on your lab from last week, we should be able to perform either a Bromine test or a Potassium permanganate test to determine if we made an alkene (or still just have our starting alkane.....fingers crossed we didn't do all the work and not make any product!) Let's test our product to see if we made an alkene, answer the questions listed below: Question 1: What would the test result look like if we made the alkene product for the Bromine test? clear Question 2: What would the test result look like if we made the alkene product for the Potassium permanganate test? brown Question 3: What would the test result look like if we made the alkane product for the Bromine test (NO UV…
