Question

Some of the properties of the two species, \( \text{NO}_3^- \) and \( \text{H}_2O \), are described below. Which one of them is correct?

• A. Dissimilar in hybridisation for the central atom with different structures
• B. Isostructural with the same hybridisation for the central atom
• C. Isostructural with different hybridisation for the central atom
• D. Similar in hybridisation for the central atom with different structures

Hint:

Check the hybridisation of the central atom in a molecule to determine the nature of its bonding.

Answer 1

The Correct Option is A

The hybridisation of the central atoms in \( \text{NO}_3^- \) and \( \text{H}_2O \) is different. In \( \text{NO}_3^- \), the nitrogen atom is sp² hybridised, while in \( \text{H}_2O \), the oxygen atom is sp³ hybridised.

Step 2: Conclusion.
The correct statement is that they are dissimilar in hybridisation for the central atom with different structures, corresponding to option (a).
