This lecture is designed for Pre-Medical and Pre-Engineering students preparing for FSc board exams, NMDCAT, ECAT, and ETEA entry tests. We begin with ethene: its molecular structure, sp2 hybridization, sigma and pi bond formation, common preparation methods (dehydration of ethanol, dehydrohalogenation of ethyl halide), and its key addition reactions. Next, we move into the molecular orbital treatment of structure, explaining how atomic orbitals combine to form bonding and antibonding molecular orbitals and how this model explains the stability of conjugated systems. Finally, we cover resonance in detail: how to draw resonance structures, the concept of resonance energy, and why benzene is far more stable than a hypothetical cyclohexatriene. This comparison of relative stability is a favorite examiner question and a must-know concept for organic chemistry. This video follows the BISE Malakand FSc Chemistry syllabus and is presented in a clear, exam-focused style with solved examples and short-cut techniques for quick revision.
