Answer:
a) Cl2
Beryllium chloride is usually prepared by the reaction of the metal with chlorine at a high temperature:
Be + Cl2 → BeCl. BeCl2
can also be prepared by carbothermal reduction of beryllium oxide in the presence of chlorine. BeCl2 can be prepared by treating beryllium with hydrogen.
On Balancing the reaction,
Be + Cl2 → BeCl. BeCl2
3Be + 2Cl2 → 2BeCl. BeCl2
Is the perfect reaction.
Beryllium chloride also forms a tetrahydrate, BeCl2•4H2O ([Be(H2O)4]Cl2).
BeCl2 is also soluble in some ethers.
