Question

AgI is more stable than AgF. Explain.​

Answer 1

Answer:

With the help of HSAB principle, we can compare the stability of various compounds or complexes. Explanation: AgI2- containing soft- soft combination due to which accoding to the HSAB principle, AgI2- well be more stable while AgF2- containing soft –hard combination, will be less stable or sometime cannot exist.

Answer 2

Answer:

• As you go down the halide column, the electronegativities of Ag and the halide approach each other.
• The bond is therefore more covalent, less ionic and less polar. And so it stops H bonding with water and is repelled by water as the H bonds to itself and turns off the non-H binders!
• F is the most electronegative atom in the periodic table, so AgF is an ionic salt solubilized by surrounding water molecules and H bonding.
• I is not very electronegative, so AgI has more covalent bonding, is less polar, and will not H bond with water.

Due to these reasons, AgI is more stable than AgF.
