Question

why frenkel defect is found in AgCl?

Answer 1

In AgCl, the size of cation( Ag+) is smaller than the anion Cl-
Sometimes cations are dislocated from its normal site to some interstitial site.It is termed as Frenkel defect.Ionic substances having large size variation between cation and anion and low coordination number generally show this defect.
Thus, AgCl shows this defect.

Hope this helps.

Answer 2

HEY MATE HERE IS YOUR ANSWER:-

This defect is shown by ionic solid this defect was pointed out by Frankel a Russian scientist in the 1926 in this defect an ion is missing from its normal position and occupies an interstitial site between the lattice points.In AgCl since there is no absence of Ions from the lattice the density remains the same ionic solid .
