Reactions of Alkenes and Alkynes
pa01000125.schoolwires.net130 CHAPTER 5 Reactions of Alkenes and Alkynes From the perspective of the chemical industry, the single most important reaction of ethylene and other low-molecular-weight alkenes is the production of chain-growth polymers (Greek: poly, many, and meros, part).In the presence of certain catalysts called initiators, many alkenes form polymers by the addition of monomers …
NOMENCLATURE OF ORGANIC COMPOUNDS
chymist.comThis compound is named 5-ethyl-2,4-dimethyloctane. Note that the branches are named in alphabetical order. II. Naming Unsaturated Hydrocarbons – Alkenes and Alkynes Rules for Naming Alkenes and Alkynes Alkenes contain at least one carbon to carbon double bond. The suffix used is –ene. Alkynes contain at least one carbon to carbon triple bond.
Naming Alkenes - Vanderbilt University
www.vanderbilt.eduNaming Alkenes Suffix: -ene Many of the same rules for alkanes apply to alkenes 1. Name the parent hydrocarbon by locating the longest carbon chain that contains the double bond and name it according to the number of carbons with the suffix -ene.

www.saplinglearning.com148 CHAPTER 4 • INTRODUCTION TO ALKENES. STRUCTURE AND REACTIVITY A. Regioselectivity of Hydrogen Halide Addition When the alkene has an unsymmetrically located double bond, two constitutionally isomeric products are possible. As shown in Eq. 4.16, only one of the two possible products is formed from a 1-alkene in sig-nificant amount.
