Hydrides

The video tutorial explains the different types of hydrides: ionic, covalent, and metallic. Ionic hydrides, formed by alkali and alkaline earth metals, are powerful reducing agents and exhibit high melting points. Covalent hydrides, such as methane and ammonia, are volatile and do not conduct electricity. They can form hydrogen bonds, leading to high boiling points. Metallic hydrides, formed by transition metals, are used for hydrogen storage due to their ability to absorb hydrogen gas. The preparation methods for molecular hydrides include reduction and hydrolysis.

How do the hydrides of groups 15, 16, and 17 behave as Lewis bases?
