\mathrm{BeCl_{2}} is a covalent compound that is soluble in organic solvents but not in water. It has a low melting and boiling point due to its weak intermolecular forces. BeCl2 is used as a precursor for the production of beryllium metal and as a reagent in organic chemistry.

  • Here are some characteristics of \mathrm{BeCl_{2}} :

    1. Physical properties:\mathrm{BeCl_{2}} is a colourless, crystalline, and hygroscopic solid at room temperature. It has a melting point of 399 °C and a boiling point of 482 °C. 

    2. \mathrm{BeCl_{2}} is soluble in polar solvents such as water and ethanol, but insoluble in non-polar solvents such as benzene and hexane.

    3. Molecular structure:\mathrm{BeCl_{2}} has a linear molecular shape, with a bond angle of 180 degrees between the beryllium and chlorine atoms.

    4. Bonding: \mathrm{BeCl_{2}} exhibits covalent bonding, with the beryllium atom forming two polar covalent bonds with each of the chlorine atoms.

    5. Reactivity: \mathrm{BeCl_{2}} is a strong Lewis acid, capable of accepting electron pairs from other molecules or atoms. It reacts with water to form beryllium hydroxide and hydrochloric acid, and with alcohols to form beryllium alkoxides and hydrogen chloride.

    6. Uses: \mathrm{BeCl_{2}} has various uses, including as a precursor for the production of beryllium metal and various beryllium compounds, as a catalyst in organic chemistry reactions, as a dopant in the semiconductor industry, and in the production of radiation shielding glass and X-ray tubes.
