Concept explainers
(a)
Interpretation:
The hydride
Concept Introduction:
Saline hydrides:
The elements present in group 1 and 2 form ionic compounds with hydrogen in which, the hydrogen is present as hydride ion
Molecular hydrides: Nonmetals form covalent molecular hydride that comprises of discrete molecules. These compounds are volatile and are bronsted acids. These are mostly formed by elements of p-blocks.
Metallic hydrides: Metallic hydrides are black, powdery, electrically conducting solids formed by heating certain elements of the d-block metals in hydrogen. Metallic hydrides releases hydrogen gas when they are treated or heated with an acid.
(b)
Interpretation:
The hydride
Concept Introduction:
Refer to part (a).
(c)
Interpretation:
The hydride
Concept Introduction:
Refer to part (a).
(d)
Interpretation:
The hydride
Concept Introduction:
