One of the sp3 hybridized orbitals overlap with an sp3 hybridized orbital from carbon to form the C-N sigma bond. The electron in the 2 pz orbital on the carbon atom then interacts with the electron in the 2 pz orbital on the oxygen atom to form a second covalent bond between these atoms. • Hybrid orbitals: atomic orbitals for each atom first combine to form new orbitals with correct geometries, which then interact to form bonds. After hybridization these six electrons are placed in the four equivalent sp3 hybrid orbitals. Further, in the process, two-hybrid orbitals form covalent bonds with each hydrogen atom and two hybrid orbitals are occupied by lone pairs. It is singly bonded to one oxygen atom and doubly bonded to the other one. This stabilises the bonding in a molecule. Note!
