What is Double Bond?
A covalent bond formed when two atoms share two pairs of electrons, consisting of one sigma bond and one pi bond. Double bonds are shorter and stronger than single bonds but allow less free rotation. They are found in alkenes and carbonyl compounds.

Foundation of organic chemistry molecular structure. Double bonds enable electrophilic addition reactions (alkenes). Triple bonds reactive to both addition and substitution (alkynes). Conjugated π systems: aromatic stability (benzene), color of organic dyes (extended conjugation), photovoltaic mater…
Molecules with many π bonds tend to be more reactive and potentially more flammable. Peroxides contain weak O−O single bonds prone to homolytic cleavage — explosion hazard. Aromatic compounds (benzene, toluene) with delocalized π systems are generally toxic (carcinogenic) — handle in fume hood with …
