Question

In the hydrogen peroxide molecule :

• A. two hydrogen atoms are connected to one of the oxygen
• B. all the four atoms are in the same plane
• C. the four atoms are arranged in a non-linear and non-planar manner
• D. $O-H$ bonds are polar but molecule is non-polar

Answer 1

Answer: (C)

the four atoms are arranged in a non-linear and non-planar manner

Hydrogen peroxide $\left(H_2{O}_2\right)$ is a nonplanar molecule with (twisted) symmetry. It is non–linear, non–planar molecule with a open book structure. The $–O–O–$ linkage is called peroxy linkage. The structure is given in the figure above.
