Question

Draw structure of $$HCl{O}_4$$.

Answer 1

Hint:A structural formula of a compound represents the structure of a particular compound. Lewis structures are formulated from the concept of the electron dot diagram. In this structure, lines are added between the atoms to represent the shared pair in a particular chemical bond.

Complete step by step answer:
We know that Hydrogen atom has only one valence electron, chlorine has seven valence electrons and oxygen atom has six valence electrons. We can draw the Lewis dot structure of $$\text{HCl}{\text{O}}_{\text{4}}$$ as follows.
                           

                          Lewis-dot structure of $$\text{HCl}{\text{O}}_{\text{4}}$$
And we can draw the structural formula of this compound as follows.
                               

Additional information:
Perchloric acid is usually found as an aqueous solution. It is a colourless compound and it is a stronger acid than nitric acid and sulfuric acid.

We can prepare at industries by two methods. In the traditional method we make use of the high aqueous solubility of sodium perchlorate $$\left(\text{NaCl}{\text{O}}_{\text{4}}\right)$$. Treating this solution with the hydrochloric acid $$\left(\text{HCl}\right)$$produces perchloric acid by the precipitation of solid sodium chloride. We can write the reaction of this preparation follows:

$$\text{NaCl}{\text{O}}_{\text{4}}+\text{HCl}\to \text{NaCl}+\text{HCl}{\text{O}}_{\text{4}}$$
Perchloric acid has various uses. It is used in making explosives, in the separation of sodium and potassium, it is used as an oxidizer, it is used in the rocket fuel ,used in plating of metals, used as catalyst, used for electropolishing of molybdenum, used as a reagent for determining the 1H-Benzotriazole etc.

Note:
$$\text{HCl}{\text{O}}_{\text{4}}$$ is commonly called perchloric acid. An alternate name for this compound is hyperchloric acid. According to the IUPAC nomenclature $$\text{HCl}{\text{O}}_{\text{4}}$$ is named as chloric (VII) acid.
