Question
Sum of π-bonds present in peroxodisulphuric acid and pyrosulphuric acid is
Solution
Peroxodisulphuric acid (H2S2O8) and pyrosulphuric acid (H2S2O7) are both sulfuric acid derivatives.
-
Peroxodisulphuric acid (H2S2O8): In this compound, each sulfur atom is bonded to four oxygen atoms. Two of these oxygen atoms are double bonded to the sulfur atom, forming two π-bonds per sulfur atom. Since there are two sulfur atoms in the molecule, the total number of π-bonds in peroxodisulphuric acid is 2*2 = 4.
-
Pyrosulphuric acid (H2S2O7): In this compound, each sulfur atom is also bonded to four oxygen atoms. Again, two of these oxygen atoms are double bonded to the sulfur atom, forming two π-bonds per sulfur atom. Since there are two sulfur atoms in the molecule, the total number of π-bonds in pyrosulphuric acid is 2*2 = 4.
Therefore, the sum of π-bonds present in peroxodisulphuric acid and pyrosulphuric acid is 4 + 4 = 8.
