(a)
Interpretation:
The formula of simplest binary hydride of each element mentioned in given periodic table has to be written.
Concept Introduction:
The compound containing hydrogen and just one other element is called binary hydride. Type of hydride formed depends upon the element present in the group. Types of binary compounds are, ionic hydride, metallic hydride and covalent hydride.
Ionic hydride: Ionic hydrides are formed by alkali metals and heavier alkaline earth metals. They contain cations and
Covalent hydride: Covalent hydrides are formed by non-metals. The compound contains hydrogen which is bonded to another element by covalent bond. Most of the covalent hydrides have relatively weak intermolecular force of attraction, so they are gas or volatile liquid at normal temperature.
Metallic hydride: Metallic hydrides are formed by
(b)
Interpretation:
The hydride has lowest boiling point should be identified.

Metallic hydride: Metallic hydrides are formed by transition metals, lanthanides and actinide metals in which hydrogen will be present in variable amount. Metallic hydride has general formula of
(c)
Interpretation:
The one hydride that gives hydrogen gas on reaction with water has to be predicted and also the balanced net ionic equation for the reaction has to be written.
