Compare the structures of `H_2O` and `H_2O_2` .

Explanation

Water exist as a discrete molecule in the gaseous state. It has a tetrahedral structure with bond angle `104^@,5.` and O-H bond length is 95,7 pm `H_2O_2` has non planer structure, O-O linkage is called peroxidelinkage. In the crystal, the dihedral angle `(111.5^@)` reduces to `90.2^@` on account of Hydrogen bonding.
