Question

define hydrides? explain the three different types of hydrides​

Answer 1

Answer:

hydride, any of a class of chemical compounds in which hydrogen is combined with another element. Three basic types of hydrides—saline (ionic), metallic, and covalent—may be distinguished on the basis of type of chemical bond involved.

Answer 2

Hydrides are the negative ion or anion of hydrogen.

• Hydride is formally the anion of hydrogen, $H^-$. They refer to compounds and ions in which hydrogen is covalently attached to a less electronegative element.
• All compounds containing covalently bound H atoms are called hydrides.
• For example, water is a hydride of oxygen and ammonia is a hydride of nitrogen.
• The Addition of a hydride anion ($H^-$) to an aldehyde or ketone gives an alkoxide anion.
