`H_2 O ` तथा `H_2 O _2 ` की संरचनाओं की तुलना कीजिए |

Explanation

In water, O atom is `sp^3` hybridised and there are two O-H bonds and two sp hybrid orbitals occupy lone pairs of electrons. Due to stronger lone pair-lone pair repulsions than bond pair-bond pair repulsions, the HOH bond decreases from `109.5^@`to `104.5^@`. Therefore, water molecule is a bent or angular molecule. `H_2O_2` has non-planar structure. In this structure, two O-O oxygen atoms are bonded to each other by a single covalent bond and each O atom is further bonded to a hydrogen atom by a single covalent bond. The two O-H bonds are in different planes. The dihedral angle between two planes is `111.5^@` in the gas phase
