Chapter 2.8, Problem 2.14BFP

(a)

Interpretation Introduction

Interpretation:

The name of the compound ${\text{SCl}}_2$ is to be determined.

Concept introduction:

The general rules for writing the systematic names for covalent compounds are as follows:

1) The element with the lower group number is named first in the systematic name. The element present in the higher group number is named second. While naming the element in the higher group number, the suffix $\text{-}ide$ follows the root name of the element.

2) If both the elements belong to the same group, the element present in the higher period number is named first.

3) To indicate the total number of atoms of each element in the compound, the Greek numerical prefixes are used. For the element named first in the systematic name, the Greek numerical prefix is used only when more than one atoms of the element are present in the compound.

(b)
