Question

Identify the correct statements from the following:
I. \(\text{In}_2\text{O}_3\) is a basic oxide.
II. \(\text{TiCl}_2\) is more ionic in nature than \(\text{TiCl}_3\).
III. Boron reacts with dinitrogen at high temperature to form BN.

• A. I, II only
• B. I, III only
• C. II, III only
• D. I, II, III

Hint:

Boron nitride (BN) is a compound of boron and nitrogen and has a wide range of industrial applications.

Answer 1

The Correct Option is D

- Statement I: \(\text{In}_2\text{O}_3\) is a basic oxide. This is correct, as \(\text{In}_2\text{O}_3\) behaves as a basic oxide. - Statement II: \(\text{TiCl}_2\) is more ionic in nature than \(\text{TiCl}_3\). This is true. \(\text{TiCl}_2\) is more ionic compared to \(\text{TiCl}_3\) due to the difference in oxidation states of titanium. - Statement III: Boron reacts with dinitrogen at high temperature to form BN. This is correct, as boron nitride (BN) is formed under these conditions. Thus, all statements are correct.
