Draw the structure of: (i) \[BeC{{l}_{2}}\] (vapour state) (ii)\[BeC{{l}_{2}}\] (solid).

Answer:

In vapour state, it has chlorobridged dimer structure which dissociates into linear monomer at\[1000{}^\circ C\]. In the solid phase, it has a polymeric structure with chlorobridges in which a halogen atom bonded to one beryllium atom uses a, lone pair of electrons to form a coordinate bond and to another atom by a covalent bond.
