Question

At STP, the element oxygen can exist as either O2 or O3 gas molecules. These two forms of the element have(1) the same chemical and physical properties(2) the same chemical properties and different physical properties(3) different chemical properties and the same physical properties(4) different chemical and physical properties

Answer 1

O2 and O3 are allotropes of Oxygen, therefore they have (4) different chemical and physical properties.

Answer 2

Answer : Option 4) Different chemical and physical properties.

Explanation : At STP (Standard Temperature and Pressure) the elemental oxygen can either exist as
`O_(2)` or
`O_(3)` in gaseous state.

Both the forms have their own physical and chemical properties.
`O_(2)` has a linear structure whereas
`O_(3)` has a bent structure. Structure also influences the properties of the elements.
