WebbAlkenes Chapter 2 30Geometric Isomers: Cis and Trans • Stereoisomers are compounds with the atoms bonded in thesame order, but their atoms have different orientations in space. • Cis and trans are examples of geometric stereoisomers andthey occur when there is a double bond in the compound. WebbNAMING 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 …
Webb8 apr. 2024 · With blue light (λ = 450 nm) in neutral to basic pH, a [2+2] photocycloaddn. can be triggered to form a cyclobutene ring in a reversible fashion. If the pH is decreased to acidic conditions, resulting in a halochromic absorption shift, photocycloaddn. on the small-mol. level is blocked due to repulsive interactions and exclusive trans-cis … WebbGeometric Isomers: compounds with the same type and number of atoms and the same chemical bonds but different spatial arrangements; such isomers cannot be interconverted without breaking a chemical bond Unsaturated Hydrocarbons: hydrocarbons that contain carbon-carbon double bonds or carbon-carbon triple bonds Addition Reaction: a reaction …

Here there is only one carbon-carbon bond, and the rotational structures (rotamers) that it may assume fall between two extremes, staggered and eclipsed. In the following description of these conformers, several structural notations are used.
