Distinguish clearly between salt-like and covalent hydrides.

1.	Distinguish clearly between salt-like and covalent hydrides.
Answer» Salt-like hydrides are also called ionic hydrides. They are formed by group 1 and 2 elements with H₂. They are basic in nature. They dissolve in water forming alkali and give H₂ gas, .e.g., NaH, CaH₂, KH etc. Covalent hydrides are formed between less electropositive or electronegative elements. Ex : B₂H₆, AlH₃, BeH₂, They are insoluble in water.
