Question

Which of the following statements is correct?

• A. Ionic hydrides are very good conductors of electricity in solid state
• B. Metallic hydrides conduct heat and electricity.
• C. Ionic hydrides do not conduct electricity in solid state
• D. Metallic hydrides are deficient of hydrogen.

Answer 1

Answer: (B), (C), (D)

Metallic hydrides are deficient of hydrogen.

Metallic hydrides are non-stoichiometric hydrides and are deficient in hydrogen. Generally, they are formed by d and f-block elements. They conduct heat and electricity.

Ionic hydrides are crystalline, non-volatile and non-conducting in solid state as ions are not free. These hydrides conduct electricity in molten or aqueous states.
