• # question_answer 24) Draw the structure of: (i) $BeC{{l}_{2}}$ (vapour state) (ii)$BeC{{l}_{2}}$ (solid).

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.
