NEET Chemistry The p-Block Elements (XII) Questions Solved


Assertion : PbI4  is not known probably because of the oxidising power of Pb(IV) and reducing
power of I-.

Reason :  Iodide stabilizes higher oxidation state.

Show Options

(C) Pb2+  is more stable because of inert pair effect. I- being larger has the tendency to lose the electron easily.

Smaller and highly electronegative elements like F- can stabilize the higher oxidation state
not I-.
