Question

out of CuCl2 and Cu2CL2 which is more stable please explain the reason ???

Answer 1

The cucl2 is more stable than Cu2cl2. The size of Cu2+ is smaller than Cu+ 

The hydration enthalpy depends on the size of the cation. Smaller the size of cation the more hydration enthalpy will be leading to more stability.

Answer 2

The CuCl2 is more stable than Cu2Cl2. The size of Cu2+ is smaller than Cu+. The hydration enthalpy depends on the size of the cation. Smaller the size of cation, more will be the hydration enthalpy. Hence more will be the stability.
