In other words, the two bonds would be formed by the overlap of the half-filled 2p y and 2p z orbitals of oxygen with the 1s orbitals of hydrogen, while the two lone pairs on oxygen would occupy the 2...In other words, the two bonds would be formed by the overlap of the half-filled 2p y and 2p z orbitals of oxygen with the 1s orbitals of hydrogen, while the two lone pairs on oxygen would occupy the 2s and 2p x orbitals. C1.2: Draw a picture showing the geometry of the overlapping orbitals that form the bonding network in allene, H 2 CCCH 2 . Then, draw a Lewis structure for the molecule, using the solid/dash wedge bond convention as necessary to indicate the correct geometry of the s bonds.
