Chapter 4, Problem 46A

(a)

Interpretation Introduction

Interpretation: The binary compounds are to be named.

Concept introduction: To name a compound, certain rules are followed. The given compounds are binary compounds.

Binary compounds are of three types:

• Type-I: Compound in which a metal forms ionic bond with a non-metal and the metal can form only one type of ions.
• Type-II: Compound in which a metal forms ionic bond with a non-metal and the metal can form more than one type of ions.
• Type-III: Compound in which a non-metal forms bond with a non-metal.

There is one another type of compound in which metal is bonded with a polyatomic ion.

When metal is bonded with polyatomic ion, rules are similar to ionic binary compounds.

Answer to Problem 46A

Xenon hexafluoride

Explanation of Solution

  ${\text{XeF}}_6$ is a compound of non-metal with non-metal. So, its name is written using rule of type-III

Rules for naming these compounds:

Type-III:

• It is name by writing the name of first element as same as element.
• Second element in anionic form and prefixes are used to denote the number of atoms. Prefix mono is not used for one element.

So, the name is xenon hexafluoride.

Answer to Problem 46A

Arsenic triodide

Explanation of Solution

  ${\text{AsI}}_{\text{3}}$ is a compound of non-metal with non-metal. So, its name is written using rule of type-III

Rules for naming these compounds:

Type-III:

• It is name by writing the name of first element as same as element.
• Second element in anionic form and prefixes are used to denote the number of atoms. Prefix mono is not used for one element.

So, the name is Arsenic triodide.
