Key Points: Physical Properties of Ethyne
- Ethyne is a colourless gas with a sweet smell when pure; impure gas may smell like garlic.
- Slightly soluble in water, but highly soluble in organic solvents like acetone and alcohol.
- The boiling point is –75°C, and it liquefies at –84°C; it is lighter than air (VD = 13).
