Molecular Shape. H2O2 molecule is a nonplanar and asymmetric molecule. It has a bent geometry due to the presence of two lone pairs of electrons on each Oxygen atom. Due to which the dipole moments in the molecule are not cancelled out. And hence there is a net dipole moment in the molecule, making H2O2 a polar molecule. There are occasions when it is important to be able to show the precise 3-D arrangement in parts of some molecules. To do this, the bonds are shown using conventional symbols: For example, you might want to show the 3-D arrangement of the groups around the carbon which has the -OH group in butan-2-ol. Example 1: butan-2-ol.CO2 Molecular Geometry. The molecular Geometry of any compound is based on the arrangement of atoms, electron pairs, and bonds. Here in CO2, both Oxygen atoms form sigma bonds with the central carbon atom and complete their octet. As a result, there are no lone pairs of electrons, but bonding pairs of electrons also repel each other.are specific because they have a shape that accommodates the shape of their substrates.
