Structure of BeCl₂:

• In BeCl₂, the two singly occupied orbitals (2s and 2p) hybridise to give two sp-hybrid orbitals. These hybrid orbitals lie along the z-direction and point in opposite directions.
• The ground state electronic configuration of Be is 1s²2s². In the exited state, one of the 2s-electrons is promoted to the vacant 2p orbital to account for its bivalency.
• One 2s and one 2p-orbital hybridise to form two sp hybridised orbitals. These two sp hybrid orbitals are oriented in opposite directions formi
