PPT-Alkene Reactions

Addition Reactions Addition is the opposite of elimination A pi bond is converted to a sigma bond Addition Reactions A pi bond will often act as a Lewis base as a nucleophile or as a Brønsted. A logical approach. Surviving Reactions. Seems like “surviving” is always the word that best describes what has to happen in this class… but I think with a little practice you’ll find this isn’t all that difficult…. The relative stabilities of related alkenes can be determined by measuring their heats of combustion.. The thermodynamic stability of the butenes increases in the order: 1-butene < cis-2-butene < trans-2-butene.. Physical Properties of Alkanes. Non polar compounds. Insoluble in water. Less dense than water and so will float on top of the water. Dissolve in organic solvents . . (. eg. dry cleaning fluid) and in each other (. London. Dr. . Ed .
