Which of the following represents saline Hydrides?
A. \[KH,\,Ca{H_2},\,Ba{H_2}\]
B. \[NaH,\,Si{H_4},\,KH\]
C. \[N{H_3},\,{B_2}{H_6},\,Al{H_3}\]
D. \[N{H_3},\,{H_2}O,\,HF\]

Hint: Saline hydride represented by \[s - \]block elements. Typically, when a chemical is formed, hydrogen provides electrons. A hydride is created when hydrogen receives electrons from the metals that are the electron donors.

Complete Step-by-Step Explanation:
Alkaline earth metals and alkali metals both produce \[MH\] type hydrides. Saline hydride is one of the dehydrating agents. They interact and take water molecules out of compounds.
The most energetic metals and hydrogen combine to form saline hydrides. Particularly with the group's alkali and an alkaline earth metal \[I\]and \[II\]elements respectively.
The hydrogen serves as the hydride ion in this group. More electropositive metal atoms join with them. And they are an ionic hydride, the structure of these is similar to the rock salts.
For example:\[NaH,\,KH,\,Ca{H_2}\]and \[Ba{H_2}\].
Therefore, saline hydrides represent \[NaH,\,Si{H_4},\,KH\]from the given options except for others.

Thus, the correct option is: (B) \[NaH,\,Si{H_4},\,KH\]

Note: It should be noted that water and saline hydrides react together to create a base and hydrogen gas. Saline hydrides are highly volatile and reactive. Basic is the same word for saline, alkali, or alkaline. Hydrogen is less electropositive than \[s - \]block elements. A hydride is the name for the hydrogen ion's anion. A reducing agent is a species that releases electrons. Even the reducing agent undergoes oxidation.
