Chapter 4: Aromatic Compounds: Transcript


Bitter almonds are the source of the aromatic compound benzaldehyde Sources of Benzene Benzene C 6 H 6 is the parent hydrocarbon of the especially stable compounds known as . Benzene is aromatic: a cyclic conjugated compound with 6 . . electrons. Reactions of benzene lead to the retention of the aromatic core. Types of Reactions. Electrophilic. substitution. Diazonium. Dr. . Sheppard. CHEM . 2412. Summer 2015. Klein (2. nd. ed. .) . sections. : 18.1, 18.2, 18.8, 18.3, 18.4, 18.5. Aromatic Compounds. Originally distinguished because of smell. Then noticed trends in reactivity. The painkiller morphine is obtained from opium, the dried sap of unripe seeps of the poppy . P. apaver. . somniferum. Amines are relatives of ammonia and are usually classified as primary, secondary or tertiary. 15-5. Molecules containing several fused benzene rings are called . polycyclic benzenoid. or . polycyclic aromatic hydrocarbons. (. PAHs. ).. Common names are used for these systems, since there is no simple naming system for them.. Dr. . Shatha. I . Alaqeel. 108 . Chem. Learning Objectives. By the end of chapter four the students will:. Understand the resonance description of structure of benzene. Understand the hybridization in benzene. 1. Chapter 14. Aromatic Compounds. Ch. 14 - . 2. About The Authors. . These PowerPoint Lecture Slides were created and prepared by Professor William Tam and his wife, Dr. Phillis Chang. . . Professor William Tam received his B.Sc. at the University of Hong Kong in 1990 and his Ph.D. at the University of Toronto (Canada) in 1995. He was an NSERC postdoctoral fellow at the Imperial College (UK) and at Harvard University (USA). He joined the Department of Chemistry at the University of Guelph (Ontario, Canada) in 1998 and is currently a Full Professor and Associate Chair in the department. Professor Tam has received several awards in research and teaching, and according to . Newehy. Chemistry Department, College of Science, King Saud University. http://fac.ksu.edu.sa/melnewehy. Aromatic . Compounds. The Structure of Benzene Ring. - . Benzene. is . the . parent hydrocarbon of . In 1825, Michael Faraday isolated a hydrocarbon called benzene, which consists of a six-carbon ring with alternating double bonds and the molecular formula C. 6. H. 6. . . Learning Goal . Describe the bonding in benzene; name aromatic compounds, and draw their line-angle structural formulas.. 22.1 Hydrocarbons. Organic Chemistry. includes almost all carbon compounds. Not limited to compounds found in living cells. Hydrocarbon: organic compound made of only hydrogen and carbon atoms. hydrocarbons. 1435-1436. 2014-2015. Learning Objectives. . Understand the. . resonance description of structure of benzene. Understand the hybridization in benzene. Understand the relation between the stability of benzene and resonance energy. 240 . Chem. 1.
