(a) Interpretation: The compound having highest melting point should be determined. Concept introduction: The binary hydrides are compounds which contain hydrogen and one other element. Binary hydrides can be classified as ionic, covalent or metallic. Covalent hydrides have lowest melting and boiling points because they have relatively weak intermolecular forces between molecules. Ionic hydrides have higher boiling and melting points, because they have stronger ionic interactions between molecules.

Solution Summary: The author explains that binary hydrides are compounds which contain hydrogen and one other element. They can be classified as ionic, covalent or metallic.
The compound having highest melting point should be determined.
Concept introduction:
The binary hydrides are compounds which contain hydrogen and one other element. Binary hydrides can be classified as ionic, covalent or metallic. Covalent hydrides have lowest melting and boiling points because they have relatively weak intermolecular forces between molecules. Ionic hydrides have higher boiling and melting points, because they have stronger ionic interactions between molecules.

Interpretation Introduction
(c)
Interpretation:
The compounds that yield H2 gas when they are mixedshould be determined.
Concept introduction:
H− ions are good proton acceptors. So, ionic hydrides react with water to give H2 and OH−
