Ques. 1AIPMT 2003
The structure of H2O2 is
- spherical
- non-planar
- planar
- linear
Answer
(2) non-planar
Solution
As per NCERT, hydrogen peroxide has a non-planar (open-book) structure.
⇒ The two O–H bonds lie in different planes; the dihedral angle is 111.5 in the gas phase and 90.2 in the solid phase.
∴ The structure of H2O2 is non-planar.
