24.4-7 Alkenes, alkynes, geometric isomers Flashcards
structural isomers
compounds with the same molecular formula but different molecular structures
alkenes
Organic compounds containing carbon-carbon double bonds
unsaturated compound
An organic compound that contains a double or triple carbon-carbon bond.
This is because they have fewer hydrogens than would otherwise be allowed.
saturated compounds
alkanes (containing maximum possible hydrogens)
alkyne
organic compounds containing carbon-carbon triple bonds
geometric isomers
differ only in the geometric relationship of their substituted groups (branches/continued chains)
In saturated compounds bonds with the double/triple bond can only be so far apart until it breaks, allowing more predictable structure
trans (configuration)
when the substituted groups of an unsaturated compound are on opposite sides of the double bond.
cis (configuration)
the substituted groups are on the same side in the double bond.
asymmetric carbon
a carbon with four different groups attached in its 4 available bonds
stereoisomers
molecules of the same structure that only differ in their arrangement in space (ie methane to methane)
