Hybridization of Be in solid BeCl₂ is

In solid BeCl₂, the beryllium chloride molecules form a polymeric structure with chloro-bridged chains. This unique arrangement plays a crucial role in determining the BeCl₂ hybridization.

Each beryllium (Be) atom in the solid state is surrounded by four chlorine (Cl) atoms. Two of these are terminal chlorine atoms bonded directly to the beryllium, while the other two are bridged chlorine atoms shared with adjacent Be atoms in the chain.

The geometry around each beryllium atom can be described as tetrahedral due to the presence of four bonding domains. To achieve this tetrahedral structure, the BeCl₂ hybridization of the beryllium atom must be sp³.

Summary of BeCl₂ Hybridization in the Solid State

• Solid BeCl₂ forms a polymeric structure with chloro-bridged chains.
• Each beryllium atom is bonded to four chlorine atoms (two terminal and two bridged).
• The hybridization of beryllium in BeCl₂ is sp³, resulting in a tetrahedral geometry.

This understanding of BeCl₂ hybridization highlights the significance of its solid-state structure in determining the chemical bonding and geometry of the compound.
