Vedclass · Answer

(D) The correct pairings are as follows:$1.$ Dehydrating agent: Concentrated sulphuric acid $(H_2SO_4)$ is a well-known dehydrating agent that removes water molecules from compounds. Thus, $(1-q)$.$2.$ In preparation of firecrackers: Sulphur is commonly used in the manufacturing of gunpowder and firecrackers. Thus, $(2-s)$.$3.$ Weak bleaching agent: Sulphur dioxide $(SO_2)$ acts as a weak bleaching agent, especially for delicate materials like wool and silk. Thus, $(3-p)$.$4.$ Lightest gas: Dihydrogen $(H_2)$ is the lightest gas in the periodic table. Thus, $(4-r)$.Therefore, the correct sequence is $(1-q), (2-s), (3-p), (4-r)$.
