Question:
What are metallic/interstitial hydrides? How do they differ from molecular hydrides?
Solution:
Metallic hydrides are those compounds which are formed when the transition element reacts with hydrogen. Eg. CaH₂, LiBH₄
Molecular hydrides are formed by the combination of an element which is having comparable higher electronegativity with hydrogen. Eg. H₂O, B₂H₆
