MCQ
Which ionic hydride is stable upto its melting point?
- ANaH
- B$CaH_2$
- ✓LiH
- D$BaH_2$
✓
Answer
Correct option: C.
LiH
- LiH
All ionic hydrides of group I and group II decompose before their melting point except LiH.
LiH is stable upto its melting point.
The ionic character of the bonds in hydrides increases from LiH to CsH and their stability decreases in the same order.
