BeCl₂ is ionic and readily dissolves in water.

The small size and high polarizing power of Be²⁺ distorts the water molecule, weakening the O-H bond and facilitating hydrolysis.

The large size of Cl^- makes it easily displaceable by water.

BeCl₂ has a linear structure, making it susceptible to nucleophilic attack by water.

BeCl₂ forms strong hydrogen bonds with water, leading to its hydrolysis.
