Question

write four characteristics of ionic hydride ​

Answer 1

Answer:

Ionic hydride has both high melting point and the boiling point as all metal compounds usually do. They have high density since these are stable molecules. They conduct electricity in molten state liberating a diatomic molecule of hydrogen gas at the anode.

Answer 2

Characteristics of ionic hydrides are as follows:-

• An ionic hydride refers to the compound formed when hydrogen reacts with elements of the s - block.
• The general formula of ionic hydride formed from Group - 1 elements is MH, for example, LiH, NaH, etc while that formed from the Group - 2 elements is MH₂ type, for example, Ca(OH)₂, Mg(OH)₂ etc
• Ionic hydrides are crystalline solids in nature.
• They have high melting or boiling points due to the strong intermolecular forces of attraction.
• In molten state, they are good conductors of electricity.
• They resemble NaCl, so also called saline hydrides.
