The statement that describes oxygen gas, O2(g), and ozone gas, O3(g) is option 3 (They have different molecular structures and different properties).
Oxygen is a non-metallic element belonging to group 6 of the periodic table. It is a diatomic gas which is colourless, odourless and tasteless.
Structurally, oxygen atom has six valence electrons and can acquire a stable octet electronic configuration by forming a double covalent bond when uniting with another oxygen atom to form an oxygen molecule.
Ozone is an unstable triatomic gaseous molecule of oxygen. it is formed from atmospheric oxygen by lightning flashes.Ozone is also a more powerful oxidizing agent than oxygen.
Ozone is a pale-blue gas with characteristic smell like that of dilute chlorine.
Therefore oxygen gas has a different molecular structure( it is datomic) and different properties( it is colourless) from ozone gas.
