Question

What reagents would be required to synthesize hex-2-yne starting with acetylene?

Answer 1

To synthesize hex-2-yne starting with acetylene, you would need Sodium amide, Carbon dioxide, and Bromine as reagents. The reaction would proceed in several steps involving the formation of an intermediate compound and subsequent reactions.

Step-by-step explanation:

To synthesize hex-2-yne starting with acetylene, you would need the following reagents:

• 1. Sodium amide (NaNH2)
• 2. Carbon dioxide (CO2)
• 3. Bromine (Br2)

The reaction would proceed in the following steps:

1. First, acetylene would react with sodium amide to form an intermediate compound called sodium acetylide.
2. Then, sodium acetylide would react with carbon dioxide in the presence of heat and pressure to form a carboxylic acid derivative.
3. Finally, the carboxylic acid derivative would undergo bromination with bromine to yield hex-2-yne.
