Answer:
Correct Answer: 5. (b)
Solution:
- The structures of beryllium chloride in the solid state and vapour phase, respectively are dimeric and chain. In vapour phase at above $900^{\circ} \mathrm{C}, \mathrm{BeCl}{2}
\mathrm{Cl} -\mathrm{Be}-\mathrm{Cl} \mathrm{BeCl}{2} \mathrm{Be} 2+2=4 s p 900^{\circ} \mathrm{C} \mathrm{BeCl}{2} \mathrm{Be}{2} \mathrm{Cl}_{4}$.
