Structure of Benzene | Kekulé, Resonance & Dewar Structures

Structure of Benzene | Kekulé Structure, Resonance Theory & Dewar Structures In this lecture by Kifayat Chemistry Lectures (KCL), we explore the structure of benzene (C₆H₆), one of the most important topics in organic chemistry. Learn how scientists developed models of benzene and why the Kekulé structure alone cannot fully explain its properties. Topics covered in this lecture: Discovery of benzene by Michael Faraday in 1825 Molecular formula (C₆H₆) and empirical formula (CH) Degree of unsaturation (IHD) of benzene Early proposed structures of benzene Kekulé structure of benzene (1865) Alternating single and double bonds in benzene Problems and limitations of the Kekulé model Why benzene favours substitution rather than addition reactions Resonance theory and the resonance hybrid of benzene Equivalent carbon–carbon bond lengths in benzene Kekulé and Dewar structures Stability and aromatic character of benzene Who should watch this lecture? This lecture is suitable for: Cambridge International AS & A Level Chemistry (9701) Cambridge O Level Chemistry IGCSE and GCSE Chemistry FSc Part I & Part II Chemistry Class 11 and Class 12 Chemistry MDCAT and other chemistry entrance examinations Students studying organic chemistry at high-school level At Kifayat Chemistry Lectures, our goal is to make chemistry concepts clear, logical, and easy to understand through well-organized explanations and board-based lectures.
