Hybridisation of BeCl2 in gaseous state
In gaseous state, BeCI2 exists as linear molecule, (CI − Be − CI). It has hybridisation.
CI − Be − CI
Structure of BeCI2
In gaseous state
Hybridisation of BeCl2 in solid state –
Be in the excited state with the configuration 1s2 , 2s12px12py02pz0 undergoes sp3 hybridisation. Two half-filled hybrid orbitals will form normal covalent bond with two CI-atoms. The other two CI- atoms are coordinated to Be-atom by donating electron pairs into the empty hybrid orbitals.
