Detailed Solution

The dipole moment of H2O2 is 2.1 Debye, which shows that hydrogen peroxide (H2O2) has a non-linear and bent structure.

What is Dipole Moment?

  • Dipole moment is a way to measure how polar a molecule is.
  • It shows how much positive and negative charges are separated inside a molecule.
  1. Measured in Debye (D) units.
  2. Zero dipole moment means linear or symmetrical structure.
  3. Non-zero dipole moment means bent or angular structure.

Dipole Moment of H2O2

  • Hydrogen Peroxide (H2O2) has a dipole moment of 2.1 Debye (D).
  • This high value shows significant charge separation and a bent shape.

What Does 2.1 D Mean for Structure?

  • The molecule is not linear.
  • The structure is bent, non-planar, like an open book.
  • Bond angles are less than 120°.
  • O–O bond is central, with H atoms attached on both sides.

Final Conclusion

In simple words, because the dipole moment of H2O2 is 2.1D, it has a bent, non-linear structure. This results in an uneven charge distribution, making H2O2 a polar molecule.
