Question

What according to Fajans rules leads to increased ionic character? (A) Large cation and small anion (B) Small cation and small charge on cation (C) Small cation and large charge on cation (D) Large cation and large charge on cation

Tardigrade Admin · Accepted Answer

According to Fajans rule small cation, high charge on cation and large anion lead to increased covalent character or inversely we can say large cation, small charge on cation and small anion leads to increased ionic character.
