Structure of Benzene | Arenes and Halogen Compounds | CAIE A Level Chemistry 9701 (A2)

Explain the structure of benzene, why its delocalised ring makes it stable, and name substituted benzene compounds for A Level Chemistry. ▶ Try Alt Academy free: https://trial.altacademy.org/?utm_sou... Arenes for CAIE A Level Chemistry (9701). Bilal Hameed explains what makes a compound aromatic, how sp2 hybridisation and overlapping p orbitals give benzene its delocalised π system, and the bond-length evidence for it. The lesson ends with the naming rules for substituted benzene rings, ready for the electrophilic substitution reactions that follow. In this lesson • Aromatic vs aliphatic compounds, and where arenes fit among hydrocarbons • Benzene's shape: sp2 carbons, 120° bond angles and a planar ring • How six p orbitals overlap to form a delocalised π system above and below the ring • Bond-length evidence: benzene's carbon–carbon bonds sit between a single and a double bond • Why the delocalised ring is stable yet attracts electrophiles • Naming substituted benzenes: numbering, lowest locants and alphabetical order Chapters 0:00 Arenes and aromatic compounds 1:50 The structure of benzene 3:35 Overlapping p orbitals and the delocalised π system 5:10 Six delocalised electrons in a planar ring 7:10 Bond lengths, stability and benzene derivatives 10:30 Naming and numbering substituted benzenes Next lesson ▶ Electrophilic Substitution:    • Electrophilic Substitution | Arenes and Ha...   — Alt Academy: courses in all major subjects across A Level, International GCSE and O Level.
