PbI 4 does not exist because Pb - I bond initially formed during the reaction does not release enough energy to unpair 6 s2 electrons and excite one of them to higher orbital to have four unpaired electrons around lead atom.

Q. Assertion : $P b I_{4}$ of lead does not exist.
Reason : $P b - I$ bond initially formed during the reaction does not release enough energy to unpair $6 s^{2}$ electrons.

If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.

If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.

If the Assertion is correct but Reason is incorrect.

If the Assertion is incorrect and Reason is correct._

$P b I_{4}$ does not exist because $P b - I$ bond initially formed during the reaction does not release enough energy to unpair $6 s^{2}$ electrons and excite one of them to higher orbital to have four unpaired electrons around lead atom.
