Aug 11, 2020 · The stability of alkene can be determined by measuring the amount of energy associated with the hydrogenation of the molecule. Since the double bond is breaking in this reaction, the energy released in hydrogenation is proportional to the energy in the double bond of the molecule.

1: find the longest chain containing the 2bl bond, and name it using "ene" as the suffix 2: number the C atoms in the chain, beginning at the end nearer the double bond 3: number the substituents and write the name 4: for cycloalkenes, the double bond is between C1 and C2, and substituents receive the lowest possible numbers 5: a -CH 2 - substituent is a methylene group, a H 2 C=CH- group is a ...

Mar 20, 2019 · Alkenes are aliphatic homologous series of hydrocarbon which form unsaturated hydrocarbon. They have the general molecular formula CnH2n, where n are positive integers. These compounds are unsaturated because they contain carbon-carbon double bonds where the two carbons are bonded together by one pi bond and one sigma bond.

In disubstituted alkenes, cis are less stable than trans - this can be rationalized by imagining steric strain between the two groups on the same side of the double bond in the cis stereoisomer. Any reaction that can interconvert the stereochemistry of a double bond will favor the trans isomer because of its stability. 6.6 Stability of alkenes
