He said:
Ag+ is small in size, and I- is large is size
So the degree of polarisation of the AgI is higher than those of AgBr and AgCl
>>the compound posses covalent character. This makes Ag-I bond shorter. Thus, the lattice enthalpy of AgI is higher.
I replied:
Ionic compounds with covalent character posses weakened lattice, the lattice enthalpy should lowered.
