Chapter 22: Problem 9

Give the name of (a) an ionic hydride and (b) a covalent hydride. In each case describe the preparation and give the structure of the compound.

Short Answer

Expert verified
The ionic hydride is Sodium Hydride (NaH), prepared by combining sodium and hydrogen, and has an ionic structure with Na+ cations and H- anions. The covalent hydride is Hydrogen Chloride (HCl), prepared by combining hydrogen and chlorine gases, and has a covalent structure where the H and Cl atoms share a pair of electrons.

Step by step solution

01

Name of Ionic Hydride and its Preparation

A common example of an ionic hydride is Sodium Hydride (NaH). It is typically prepared by direct combination of its two constituents, sodium (Na) and hydrogen (H2), in a reaction: \(2Na + H2 \rightarrow 2NaH\). The structure is ionic, with Na+ cations and H- anions.
02

Name of Covalent Hydride and its Preparation

A common example of a covalent hydride is hydrogen chloride (HCl). It is typically prepared by the direct combination of hydrogen (H2) and chlorine (Cl2) gases, in a reaction: \(H2 + Cl2 \rightarrow 2HCl\). The structure of HCl is covalent, with the H and Cl atoms sharing a pair of electrons.
