Question

The structure of Beryllium chloride ($BeCl_2$) is highly dependent on its physical state and temperature. Which of the following accurately tracks the structure of $BeCl_2$ from solid state $\rightarrow$ vapor phase (< 1200 K) $\rightarrow$ vapor phase (> 1200 K)?

Prashant Kotian · Accepted Answer

Correct answer: B. In the solid state, exists as a highly stable, halogen-bridged polymeric chain. When heated into the vapor phase below 1200 K, it breaks down into a chlorobridged dimer (). Above 1200 K, it further dissociates into an sp-hybridized linear monomer ().
