Question

Give the names of the following compounds.
(i) \[HClO\]
(ii) \[HCl{O_2}\]
(iii) \[HCl{O_3}\]
(iv) \[HCl{O_4}\]

Answer 1

Hint: Chemical name is used to represent any chemical compound. For different chemical compounds, different unique chemical names are applied.

Complete step-by-step answer:
Acids are chemical compounds with a pH of less than 7. Acids generally dissociate when added to water to give hydrogen ions.
(i) \[HClO\]
The structure is shown below.

Image: \[HClO\]
Here, one oxygen atom is bonded to one hydrogen atom and one chlorine atom.
The chemical name of \[HClO\]is hypochlorous acid. It is a weak acid.
(ii) \[HCl{O_2}\]
The structure is shown below.

Image: \[HCl{O_2}\]
Here, the chlorine atom is bonded with an oxygen atom by a double bond and one oxygen atom by a single bond and one oxygen atom is bonded with hydrogen by a single bond.
The chemical name of \[HCl{O_2}\]chlorous acid. It is a oxoacid of chlorine.
(iii) \[HCl{O_3}\]
The structure is shown below.

Image: \[HCl{O_3}\]
Here the chlorine atom is bonded with two oxygen atoms by a double bond and one oxygen atom by a single bond and the oxygen atom is bonded with hydrogen by a single bond.
The chemical name of \[HCl{O_3}\] is chloric acid.It is a colourless liquid.
(iv) \[HCl{O_4}\]
The structure is shown below.

Image: \[HCl{O_4}\]
Here, the chlorine atom is bonded with three oxygen atoms by a double bond and one oxygen atom by a single bond and the oxygen atom is bonded with hydrogen by a single bond.

The chemical name of \[HCl{O_4}\]is perchloric acid. It is a colourless, odourless solution.
Note: The given chemical compounds, hypochlorous acid, chlorous acid, chloric acid, and perchloric acid come under chlorine acid. Hydrochloric acid also come under chlorine acid.
