Question

Which one of the following properties is generally not applicable to ionic hydrides?

• A. Non-volatile
• B. Non-conducting in solid state
• C. Crystalline
• D. Volatile

Hint:

Ionic hydrides are non-volatile, crystalline, and do not conduct electricity in the solid state.

Answer 1

The Correct Option is D

The question asks which property is generally not applicable to ionic hydrides. To identify the correct answer, we need to understand the properties of ionic hydrides.

Ionic Hydride Properties:

• Non-volatile: Ionic hydrides are non-volatile as they form stable compounds with strong ionic bonds, making it difficult for them to transition into gaseous form.
• Non-conducting in solid state: In the solid state, ionic hydrides do not conduct electricity because the ions are in fixed positions in the crystal lattice and are not free to move.
• Crystalline: Ionic hydrides are crystalline solids. The ions in the compound form a regular lattice structure which is typical of crystalline materials.
• Volatile: Typically, ionic hydrides are not volatile because they do not readily evaporate or sublime due to the strong ionic bonds holding the ions together in a solid lattice.

Based on the above characteristics, the property that is generally not applicable to ionic hydrides is being volatile. Volatility is associated with substances that can easily evaporate or convert into a gaseous state at relatively low temperatures, which is not the case for ionic hydrides.

Conclusion: The correct answer is Volatile.
