Question:
Which of the following is false about \(\mathrm{H}_2\mathrm{O}_2\)?
Which of the following is false about \(\mathrm{H}_2\mathrm{O}_2\)?
Show Hint
H\(_2\)O\(_2\) has a skew (non-planar) structure due to hindered rotation around O–O bond.

- Act as both oxidising and reducing agent
- Two OH bond lie in the same plane
- Pale blue liquid
- Can be oxidised by ozone
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
Hydrogen peroxide has a non-planar "open book" structure.
Step 2: Detailed Explanation:
(A) True: H\(_2\)O\(_2\) can be both oxidised and reduced.
(B) False: The two OH bonds are not in the same plane; H\(_2\)O\(_2\) has a dihedral angle of about \(111.5^\circ\).
(C) True: Pure H\(_2\)O\(_2\) is a pale blue liquid.
(D) True: Ozone oxidises H\(_2\)O\(_2\) to O\(_2\).
Step 3: Final Answer:
Two OH bonds lie in the same plane is false.
