The structure of H2O2 is

  1. spherical
  2. non-planar
  3. planar
  4. 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.
