Sigma Bond:A sigma bond is a type of covalent bond formed by the end-to-end overlapping between atomic orbitals, which serves as the primary bonding interaction between atoms in a molecule.
sp2 Hybrid Orbitals:sp2 hybrid orbitals are formed by mixing one s orbital and two p orbitals from an atom, creating three hybridized orbitals used for forming strong sigma bonds with other atoms.
Ethylene:Ethylene (C2H4) is an organic compound consisting of a carbon-carbon double bond, where both sigma and pi bonds play critical roles in its chemical structure and reactivity
