Chapter 4, Problem 4.66E

Interpretation Introduction

(a)

Interpretation:

The name of the binary covalent compound ${\text{PCl}}_{\text{3}}$ is to be stated.

Concept introduction:

The compounds which are formed by mixing a nonmetal or two nonmetal elements with one metalloid are known as binary covalent compounds.

The rules for naming the binary covalent compounds are as follows:

• The element’s name that has the lower electronegativity will be written first.

• The element that has the higher electronegativity, its stem name is written first followed by the addition of the suffix –ide at the end.

• The number of elements is represented by the prefix like, mono for $1$ element, di for $2$ elements, tri for $3$ elements, tetra for four elements, penta for $5$ elements, hexa for $6$ elements and so on.
