# Organic Chemistry Exercise ## 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.
