The video tutorial explains benzene's properties, structure, and aromaticity. Benzene is a colorless liquid with a boiling point of 80°C, found in crude oil. Its structure consists of six carbon atoms in a ring, each bonded to a hydrogen atom, making it a hydrocarbon. The unpaired electrons in benzene become conjugated, giving it aromaticity. Aromaticity refers to the stability from electron conjugation in ring-shaped molecules. Benzene is carcinogenic and reacts mainly through substitution, preserving its aromaticity. Electrophiles, like Cl+ and NO2+, are crucial for benzene reactions, leading to compounds like trinitrotoluene.
