Interpretation Introduction

Interpretation:

The systematic name of the molecule has to be identified.

Concept introduction:

According to the nomenclature, when two nonmetals are present in the given compound the name of the compound is given as follows,  For example, $\text{ HCl}$.  According to the name of the compound, first give the name for the hydrogen followed by the second element, changing the ending of its name to –ide.  Chlorine called as chloride.  Therefore $\text{ HCl}$ is hydrogen chloride. Similarly, $\text{HI}$ is hydrogen iodide.  One pair of elements to form several different binary molecular compounds.  In these cases, using of Greek prefixes to denote the number of atoms of each element present.

Greek prefixes are given below,

If prefix mono substituted is generally omitted for the first element. For example, ${\text{SO}}_{\text{2}}$ is named sulfur dioxide, is not monosulfur dioxide. Moreover, only one atom in a prefix for the first element, no needs to mention mono or di etc. In addition, for ease of pronunciation, we usually eliminate the last letter of a prefix that ends in o or a when naming an oxide. Thus, ${\text{N}}_{\text{2}}{\text{O}}_{\text{5}}$ is Dinitrogen pentoxide, rather than Dinitrogen pentoxide.

If any halogens are present in the molecule in suffix, the name of the halogens as follows.
