Question

Name the inorganic molecule which is known as ozonized oxygen?

Answer 1

When a silent electric discharge is passed through dry oxygen, ozone is formed. Oxygen is never converted into ozone completely and we always obtain a mixture of oxygen and ozone. This mixture is called ozonized oxygen. Thus, ozone is an ozonized oxygen.

Complete answer: Ozone is the inorganic molecule known as ozonized oxygen.
Ozone is an allotropic form of oxygen. Its molecular formula is ${O_3}$ . The occurrence of ozone is in small amounts, in the upper layer of the atmosphere, where it is formed due to the action of ultraviolet rays on the oxygen of the air. It is also present in sea water where it is formed due to reaction of fluorine with water.
Ozone is prepared in a specially designed apparatus called an ozoniser. There are two types of ozonisers commonly used, Siemens and the Brodie ozoniser. The reaction is as follows;
$3{O_2}\xrightarrow[{disch\arg e}]{{electric}}2{O_3}$ $\Delta H = + 284.5kJmo{l^{ - 1}}$
On subjecting oxygen to silent electrical discharge, ozonized oxygen containing $10-15\%$ ozone is formed. By taking following precautions, the yield of ozone can be increased in the ozonized oxygen;
Only pure and dry oxygen should be used.
The ozoniser should be perfectly dry.
A fairly low temperature (around ${0^0}C$ ) should be maintained.
There should be no sparking.
Hence Ozone is known as ozonized oxygen.

Note:
Ozone in the upper atmosphere is formed in two steps;
Photodissociation of oxygen by ultraviolet radiations of wavelength less than 240 nm.
${O_2}\xrightarrow{{h\nu }}{O^.} + {O^.}$
Oxygen atoms are really diradicals with two unpaired p-orbital electrons, but are represented with a single electron here.
Combination of highly reactive oxygen atoms with oxygen molecules.
${O_2} + {O^.}\xrightarrow{{h\nu }}{O_3}$ .
