Concept explainers
Interpretation:
The formula of the simplest binary hydride of each given element in the periodic table should be determined.
Concept introduction:
Binary hydride consists of an element bonded to hydrogen and hydrogen acts as the more electronegative species.
Interpretation:
Hydride having a lowest boiling point should be determined.
Concept introduction:
The boiling point of a liquid is defined as the temperature at which the liquid boils and turns to vapor.
Interpretation:
Hydride which gives H2 gas on reacting with water should be determined and the balanced net ionic equation for the reaction should be determined.
Concept introduction:
Binary hydride consists of an element bonded to hydrogen and hydrogen acts as the more electronegative species.
When metal hydrides react with water and gives hydrogen gas, metal ion and hydroxide ion.
Interpretation:
Hydride which reacts with water to give an acidic solution and the hydride which give basic solution should be determined.
Concept introduction:
Binary hydride consists of an element bonded to hydrogen and hydrogen acts as the more electronegative species.
When nonmetallic hydrides react with water and give acidic solution whereas metallic hydrides react with water and give basic solution.
