Question

Assertion (A): PbCl4 is less stable than PbCl2 and decomposes on gentle heating to PbCl2 and Cl2. Reason (R): The 6s^2 electrons of Pb are held tightly (inert pair effect), so the +2 state is favoured over +4.

Accepted Answer

Both A and R are true and R is the correct explanation of A

Answer

Both A and R are true but R is not the correct explanation of A

Answer

A is true but R is false

Answer

A is false but R is true

Assertion (A): $PbCl X_{4}$ is less stable than $PbCl X_{2}$ and decomposes on gentle heating to $PbCl X_{2}$ and $Cl X_{2}$ . Reason (R): The $6 s^{2}$ electrons of Pb are held tightly (inert pair effect), so the +2 state is favoured over +4.
