Assertion : `PbI_(4)` doesn't exist and converts into `PbI_(2) and I_(2)` spontaneously at room temperature but `PbCl_(4)` needs heatin to convert into `PbCl_(2) and Cl_(2)`.
Reason : `Pb^(2+)` is more stable than `Pb^(4+)`due to inert pair effect.

Options

A. If assertion is true but the reason is false
B. If assertion is false but reason is true
C. If both assertion and reason are true and the reason is the correct explanation of assertion
D. If both assertion and reason are true and the reason is not the correct explanation of assertion

Answer

D

Explanation

`underset("oxidixing agent")(Pb^(4+))+underset("strong reducing agent")(4I^(-)) to PbI_(2)+I_(2)`
Hence, `PbI_(4)` does not exist
`underset("oxidixing agent")(Pb^(4+))+underset("not good red, agent like " I^(-))(4Cl^(-)) to underset("unstable")(PbCl_(4)) overset("above")underset(50^(@)C)(to) PbCl_(2)+Cl_(2)`
Since `Cl_(2)` is a strong oxidizing agent, hence `Cl^(-)` is poor reducing agent, therefore `PbCl_(4)` does from bur decomposes on heating.
