Below is the Lewis structure of the hydrogen peroxide (H2O2) molecule.
The Correct Answer and Explanation is :
The Lewis structure of hydrogen peroxide (H₂O₂) consists of two oxygen (O) atoms and two hydrogen (H) atoms. Each oxygen atom forms a single bond with a hydrogen atom and is also connected to the other oxygen atom via a single bond. The structure follows the octet rule, ensuring that each oxygen atom has a complete valence shell.
Correct Lewis Structure of H₂O₂:
- Hydrogen (H) atoms each have one valence electron and need one bond to complete their duet.
- Oxygen (O) atoms each have six valence electrons and need two additional electrons to complete their octet.
- The oxygen atoms form a single bond (O–O) between them.
- Each oxygen also forms a single bond with a hydrogen atom.
- The remaining lone pairs are placed around the oxygen atoms to complete their octets.
Explanation (300 words):
Hydrogen peroxide (H₂O₂) is a simple peroxide where two oxygen atoms are covalently bonded to each other and each is bonded to a hydrogen atom. To determine its Lewis structure, we count the total number of valence electrons:
- Hydrogen (H) atoms contribute 1 electron each (2 × 1 = 2 electrons).
- Oxygen (O) atoms contribute 6 electrons each (2 × 6 = 12 electrons).
- Total valence electrons = 2 + 12 = 14 electrons.
Now, we arrange the atoms with O–O in the center and attach H atoms to each oxygen. Each bond (single) uses 2 electrons, so four electrons are used for the two O–H bonds and two for the O–O bond, leaving 8 electrons to distribute as lone pairs.
Each oxygen needs 8 valence electrons, and after bonding, they already have 4 each (from bonds). The remaining electrons are placed as lone pairs, ensuring each oxygen gets a full octet.
H₂O₂ has a bent shape due to the lone pairs on oxygen, causing repulsion. The molecule exhibits hydrogen bonding, making it more stable in liquid form.
Now, I will generate an image of the Lewis structure of H₂O₂.
