Question

Compare the structures of $H_{2}O$ and $H_2{O}_2$.

Answer 1

In gaseous phase, water molecule has a bent form with a bond angle of ${104.5}^{\circ }$. The O - H bond length is 95.7 pm. The structure can be shown as:

Hydrogen peroxide has a non-planar structure both in gas and solid phase. The dihedral angle in gas and solid phase is ${111.5}^{\circ }$ and ${90.2}^{\circ }$ respectively. The O-O linkage present on the molecule called 'peroxide' linkage.
