(A):

{SiH}_4

AlH_3

and

{NH}_3

are ionic hydrides

(R):Ionic hydrides do not react with water

View answer and explanation

Correct option: D

Both

(A)

and

(R)

are false

Option D is correct because the assertion that SiH4, AlH3, and NH3 are ionic hydrides is false, as they are covalent. Also, the reason that ionic hydrides do not react with water is also false, as they react vigorously.

Hydrogen accepts an electron to form inert gas configuration. In this it resembles

\mathrm{CaC}_2+\mathrm{H}_2 \mathrm{O} \longrightarrow \mathrm{Ca}(\mathrm{OH})_2+' \mathrm{X}\,'

\mathrm{Mg}_2 \mathrm{C}_3+\mathrm{H}_2 \mathrm{O} \longrightarrow \mathrm{Mg}(\mathrm{OH})_2+'\mathrm{Y}\,'

The products '
