PPT-Alkanes, Alkenes, Alkynes

Straight chain alkanes will have symmetrical electronegativities so they will behave as nonpolar molecules Since like dissolves like the alkanes will all be soluble in eachother However since water is polar alkanes will NOT dissolve in water think of pouring oil on water . 6 286 Relative Stability of Alkenes Based On Molar Heats of Hydrogenation H hyd 276 kcalmol H hyd 286 kcalmol Trans cis brPage 3br Relative Stability of Alkenes Based On Molar Heats of Hydrogenation 327 kcalmol 297 kcalmol 280 kcalmol 286 kcalmol 1 Chemical Tests for Alkanes, Alkenes, and Aromatic Compounds Introduction There are four types of hydrocarbons : alkanes, alkenes, alkynes, and aromatic compounds, each type with different chemical Alkenes and Alkynes I:. Properties and Synthesis.. Elimination Reactions. of Alkyl Halides. Copyright © 2014 by John Wiley & Sons, Inc. All rights reserved.. About The Authors. . These PowerPoint Lecture Slides were created and prepared by Professor William Tam and his wife, Dr. Phillis Chang. . In a reaction catalyzed by mercuric ion, water can be added to alkynes to give enols, which then tautomerize to give ketones.. Hydration follows Markovnikov’s rule—terminal alkynes give methyl ketones:. Preparation of alkenes. Preparation of alkenes continued. Dehydration of alcohols. The H and OH are removed from adjacent carbons.. E.g. ethanol may be heated with . sulphuric. acid to create . ethene. Sources . and Uses of Alkanes. Petro. leum. , which literally means . rock . oil. is the main source of alkanes. Petroleum is a mixture of hundreds of hydrocarbons, mostly alkanes with varying numbers of carbons and varying degrees of branching. Hydrocarbons . Essential idea. Structure, bonding and chemical reactions involving functional group inter-conversions are key strands in organic chemistry.. Learning outcomes . Understand:. Alkanes. have low reactivity and undergo free-radical substitution reactions.. . H—. O. H. C. C. +. O. H. C. C. H. Acid-Catalyzed Hydration of Alkenes. reaction is acid catalyzed; typical hydration medium is 50% H. 2. SO. 4. -50% H. 2. O. Follows Markovnikov's Rule. H. ydrohalogenation. Conformational and Geometrical Isomerism. Hydrocarbons. . are . compounds that contain only carbon and hydrogen. . There are three main classes of hydrocarbons, based on the types of carbon–carbon bonds present. . The Structure of Alkanes. Nomenclature of Organic Compounds. Alkyl groups. Numbering the parent carbon chain. The root name is that of the longest continuous carbon chain (. parent carbon chain. ) . Groups attached to the main chain are called . TIER 5. Predict and explain trends in boiling points of members of a homologous series. Discuss the volatility and solubility in water of compounds containing the functional groups: compounds up to six carbon atoms with one of the following functional groups: alcohols, . Division of Material. Alkenes and Alkynes are very versatile molecules in Organic Chemistry. As a result, there is a lot of information we need for them. . To make it manageable, the information is divided into two chapters.. Crude oil, hydrocarbons and alkanes. Carbon compounds as fuels and feedstock. Crude. oil. A. finite resource. Consisting. mainly of plankton that was buried in the mud, crude oil is the remains of ancient biomass.. . initiated. by an hydride shift. Yann . Odabachian. 25.09.2012. Concept of redox . processes.
