The incorrect statement among the following is
The maximum covalency of a non-metallic group 15 element ' E ' with weakest $\mathrm{E}-\mathrm{E}$ bond is :
Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A) : Both rhombic and monoclinic sulphur exist as $$\mathrm{S}_8$$ while oxygen exists as $$\mathrm{O}_2$$.
Reason (R) : Oxygen forms $$p \pi-p \pi$$ multiple bonds with itself and other elements having small size and high electronegativity like $$\mathrm{C}, \mathrm{N}$$, which is not possible for sulphur.
In the light of the above statements, choose the most appropriate answer from the options given below :
On reaction of Lead Sulphide with dilute nitric acid which of the following is not formed?
