Chapter 24, Problem 9QP

Interpretation Introduction

Interpretation:

The name of an ionic hydride and a covalent hydride is to be given, preparation for each case is to be described, and the structure of the compound is to be given.

Concept Introduction:

The hydrogen bond involves interaction between partial positive-charged hydrogen atoms and more electronegative atoms.

The electronegative atoms could be nitrogen, oxygen, fluorine, and adjacent atoms that contain a lone pair of electrons.

All those compounds that contain an element linked to hydrogen atom, in which hydrogen is considered a more electronegative species, are known as binary hydrides. It could be ionic, covalent, or interstitial.

Ionic hydrides are the hydrides in which a hydrogen atom is linked directly with an alkali metal.

Covalent hydrides are the hydridesin which a hydrogen atom is bonded to the atom of another element covalently.

Interstitial hydrides are the hydridesin which a hydrogen atom and a metal are found in constant ratio, which means hydrogen atom is combined to the metal.
