Assertion: has a high melting and boiling point.
Reason: has strong intermolecular forces.
Options:
Both assertion and reason are true, and the reason is the correct explanation of the assertion.
Both assertion and reason are true, but the reason is not the correct explanation of the assertion.
Assertion is true, but the reason is false.
Assertion is false, but the reason is true.
BeCl2 has a low melting and boiling point due to its weak intermolecular forces, which can be attributed to its simple linear structure, small size, and lack of polarity. Therefore, the assertion is false, while the reason is true.
Here are some properties of :
Physical properties: is a colorless, crystalline, and hygroscopic solid at room temperature. It has a melting point of 399 °C and a boiling point of 482 °C. is soluble in polar solvents such as water and ethanol, but insoluble in non-polar solvents such as benzene and hexane.
Molecular structure: has a linear molecular shape, with a bond angle of 180 degrees between the beryllium and chlorine atoms.
Bonding: exhibits covalent bonding, with the beryllium atom forming two polar covalent bonds with each of the chlorine atoms.
Reactivity: 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.
Toxicity: is toxic when ingested or inhaled, and exposure can lead to respiratory and skin irritation, as well as other health effects such as lung damage and cancer.
Uses: 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.
