Which of the following statements regarding N2O4 is not correct? — p Block Elements Chemistry Question

💡 Solution & Explanation

Step 1: The pyrosilicate anion, Si2O7^6-, is formed by joining two tetrahedral SiO4^4- units together. Step 2: This dimer shares exactly one corner oxygen atom between the two silicon atoms: 2*(SiO4^4-) - 1*(O^2-) = Si2O7^6-. Step 3: Thus, the anion is obtained when one oxygen of a SiO4^4- tetrahedron is shared with another SiO4^4- tetrahedron, matching option (b).
