Question

What is the difference between water and hydrogen peroxide?

Answer 1

Water is a polar compound with the chemical formula of ${H_2}O$ and hydrogen peroxide is an oxidizing agent with the chemical formula of ${H_2}{O_2}$ . water can act as a polar solvent where hydrogen peroxide can be used as an oxidizing agent. The bonds in hydrogen peroxide are weak compared to water.

Complete answer:
Hydrogen is an element with atomic number $1$ and oxygen is an element with atomic number $8$ . Both these atoms have differences in the value of electronegativity and can form different compounds like water and hydrogen peroxide.
Water is a compound with a chemical formula of ${H_2}O$ and hydrogen peroxide is a compound with a molecular formula of ${H_2}{O_2}$ .
In water there are only two $O - H$ bonds and in hydrogen peroxide there are two $O - H$ bonds and there is an extra bond which is $O - O$ bond. But this $O - O$ bond is weak and can easily undergo cleaving to form two $^ \bullet O - H$ radicals.
Due to the strong intermolecular forces and hydrogen bonding in hydrogen bonding, it has a higher boiling point than water. In water also the hydrogen bonding involves but it does not have the extent bond like $O - O$ . Thus, the boiling point of water is less than hydrogen peroxide.

Note:
The hydrogen peroxide can be used as an oxidizing agent. In the presence of hydrogen peroxide, the molecules or compounds undergo radical mechanisms. In presence of hydrogen peroxide, alkenes undergo anti-markovnikov rule to form products that are different from the products obtained in the absence of hydrogen peroxide.
