Symmetrical alkyne

WebReaction Overview: The hydrohalogenation of alkenes involves breaking a carbon to carbon double bond, followed by the electrophilic addition of a hydrogen atom and halogen. The halide will add to the more substituted carbon following Markovnikov's rule. The product is a haloalkane also called an alkyl halide. Summary of Hydrohalogenation Mechanism … WebNAMING of ALKENES/OLEFINS and ALKYNES o Parent: Longest alkyl chain + “ene” (if alkene) / “yne” (if alkyne) Propene, propyne o If the unsaturated bond is not placed on the carbon-1, put the number representing the position of the unsaturated bond between the name of the alkyl chain and the suffix, enclosing the number between two dashes (But-2 …
