Which statement correctly describes two forms of oxygen, O2 and O3?
(1) They have identical molecular structures and identical properties.
(2) They have identical molecular structures and different properties.
(3) They have different molecular structures and identical properties.
(4) They have different molecular structures and different properties.



Answer :

The two forms of oxygen, O2 and O3 is "They have different molecular structures and different properties."

Answer: Option (4) is the correct answer.

Explanation:

In an [tex]O_{2}[/tex] molecule there are two oxygen atoms and in a [tex]O_{3}[/tex] molecule there are three oxygen atoms.

So, there will be different number of electrons involved in the bonding of atoms for both [tex]O_{2}[/tex] and [tex]O_{3}[/tex] molecules.

Therefore, both of them will have different structure and reactivity.

Thus, we can conclude that the statement they have different molecular structures and different properties, correctly describes two forms of oxygen, O2 and O3.
