⚗️ Chemical & Physical Properties
Propargyl chloride is a colorless to light yellow liquid with a pungent odor, reminiscent of garlic or onion. It is a highly reactive compound due to the presence of the acetylenic triple bond in its structure.
With a molar mass of 78.50 g/mol and a density of 1.15 g/cm³, propargyl chloride is relatively light and less dense than most common food items such as water (molar mass of 18.015 g/mol, density of 1 g/cm³) and sugar (molar mass of 342.30 g/mol, density of 1.59 g/cm³).
The melting point of propargyl chloride is -128.5°C, while the boiling point is 51.8°C. These values are significantly lower than those of common food items like butter (melting point of 32°C, boiling point of 100°C) and chocolate (melting point of 34°C, boiling point varies depending on composition).
Propargyl chloride is sparingly soluble in water and exhibits low viscosity, making it easily miscible in organic solvents. This is in contrast to common food items like salt (high solubility in water) and honey (high viscosity), indicating its unique chemical properties.
