Now, as two oxygen atoms need two electrons each to complete their octets, it will share two electrons from the Carbon atom and form double bonds. "mainEntity": [{

The Lewis dot structure for any molecule or compound helps determine the arrangement of atoms in the molecule, bonds formed, and lone pairs of electrons. As carbon needs 8 electrons to complete its octet shell but carbon has only 4 electrons(two single bonds) around it. Therefore, place the remaining valence electron around oxygen first for completing its octet shell. Molecular geometry, also known as the molecular structure, is the three-dimensional structure or arrangement of atoms in a molecule. Electronegativity is the ability of atoms that determines how strongly it will attract the electrons towards itself to complete its octet. As the molecular geometry of H2O2 is bent and electron geometry is tetrahedral it shows that dipoles cannot be canceled out because they lie in two different planes. E represents the number of lone pairs attached to the central atom.
