Question

What is false about $H_2{O}_2$ ?

• A. Acts both as oxidising and reducing agent
• B. Two $OH$ bonds lie in the same plane
• C. Pale blue liquid
• D. Can be oxidised by $O_3$

Answer 1

The correct option is B Two $OH$ bonds lie in the same plane

In pure form, $H_2{O}_2$ is a pale blue liquid. It can be oxidised from -1 to 0 oxidation state as well as they can be reduced from -1 to -2 oxidation state. Hence they have a intermediate oxidation state between 0 and -2. Hence they are both oxidising and reducing agent.
$O_3$ is strong oxidising agent than $H_2{O}_2$ so it will oxidise $H_2{O}_2$.
Hydrogen peroxide ($H_2{O}_2$) is a non–linear, non–planar molecule with a open book structure. Hence, two $O-H$ bonds lie in the different planes.
