Compound A used as a potent oxidising agent is amphoteric in nature. It is the part of lead storage batteries. Compound A is:
A. \[P{b_3}{O_4}\]
B. \[Pb{O_2}\]
C. \[PbS{O_4}\]
D. \[\;PbO\]

Hint: We know that \[Pb{o_2}\] is a chemical compound that can be used to convert other compounds into different substances. \[Pb{o_2}\] is an abbreviation for the chemical formula of the compound \[3\]- bromopropane. It is also known as \[3\]- bromopropene and bromo-propane.

Complete Step by Step Solution:
A potent oxidising agent is amphoteric and can be used for various reactions. This is because the compound tends to react with both water and oxygen. The potent oxidising agent, also known as a\[Pb{o_2}\]. \[Pb{o_2}\] , is a potent oxidising agent and amphoteric. It is used to respond to different substances like acids, bases, alcohols, and some organic compounds.

We know that \[Pb{O_2}\] is used in lead storage batteries. Because \[Pb\]\[ + 4\] of this \[O.S\] , it is constantly reduced and acts as an oxidising agent. It is also known as phosphorus pentoxide. Also, \[Pb{o_2}\] is a white powder that is insoluble in water but soluble in alcohols and organic solvents. German chemist Justus von Liebig \[1833\] first discovered phosphorus pentoxide when trying to make a compound from phosphorus and oxygen. A \[Pb{O_2}\] is a chemical species with two atoms of boron and one atom of oxygen. This is a joint compound that can be found in many natural sources. \[Pb{o_2}\] is a chemical abbreviation for phosphoric acid, a chemical that can be used as a reagent in organic synthesis. It can also be used to synthesise some essential molecules.

Hence, the correct answer is option (B) PbO₂.

Note: We know that \[Pb{o_2}\] was initially discovered by a French chemist \[1891\] and then later synthesised \[1934\]by a British chemist. Also, \[Pb{o_2}\] is used for converting other compounds into different substances such as, but not limited to, alcohols, acids, amines, and ketones.
