Water (h20) is composed of the same element as hydrogen peroxide (h202) how do their properties compare?
2 answers:
The formation of compound takes place by the combination of two or more different atoms. The combination of atoms takes place in a definite proportions. Compounds with different proportions of atoms have different properties.
Water () is composed of the same element as hydrogen peroxide (
) that is hydrogen (
) and oxygen (
). The combination of hydrogen and oxygen atoms in water is in
ratio whereas the combination of hydrogen and oxygen atoms in hydrogen peroxide is in
ratio. So, the properties of water and hydrogen peroxide are different as the arrangement of atoms is different in the compound.
Hence, the correct option is they have different properties because the arrangement of atoms is different.

Answer: The correct option is A.
Explanation: The given molecules are the molecules of same element.
These molecules are considered as diatomic species.
Polar molecules are the molecules in which some polarity is present in the bond. These molecules are formed when there is some difference in the electronegativities of the elements. Example: HCl
Non-polar molecules are the molecules where no polarity is present in the bond. These molecules are formed when there is no difference in the electronegativities of the elements. Example:
The given molecules are non-polar in nature.
Hence, these molecules must be non-polar. So, the correct option is A.
