The mixed anhydride of nitrogen is: — p Block Elements Chemistry Question

💡 Solution & Explanation

Step 1: A mixed anhydride is an oxide that reacts with water to produce a mixture of two different acids. Step 2: Nitrogen dioxide / dinitrogen tetroxide (N2O4) reacts with water to form a 1:1 mixture of nitrous acid (HNO2) and nitric acid (HNO3). Step 3: Therefore, N2O4 is the mixed anhydride of nitrogen, matching option (b).
