    What is the hybrid state of \[BeC{{l}_{2}}\]? What will be the change in hybrid state of \[BeC{{l}_{2}}\] in the solid state?  

    Answer:

                    In the vapour state at high temperature (1200 K), Be is sp- hybridized and hence \[BeC{{l}_{2}}\] in linear. In the solid state, \[BeC{{l}_{2}}\] is polymeric (Refer to structure on page 10/37). In this structure, each Be has two covalent and two coordinate bonds. Therefore, in the solid state. Be has \[s{{p}^{3}}\]-hybridization.
