In a bimolecular reaction, the steric factor $$P$$ was experimentally determined to be $$4.5.$$ The correct option(s) among the following is (are)

Among the following, the correct statement(s) is (are)

The options(s) with only amphoteric oxides is (are)

Compounds $$P$$ and $$R$$ upon ozonolysis produce $$Q$$ and $$S,$$ respectively. The molecular formula of $$Q$$ and $$S$$ is $${C_8}{H_8}O.Q$$ undergoes Canninzzaro reaction but not haloform reaction, whereas $$S$$ undergoes haloform reaction but not Cannizzaro reaction


The option(s) with suitable combination of $$P$$ and $$R,$$ respectively, is (are)
