A Compound containing a double bond, that can take part in a Diels-Alder reaction.
|
Dienophile
|
|
|
An alkene + ketone .
|
Enone
|
|
|
More highly substituted alkenes are more stable than less substituted ones.
|
Fact
|
|
|
The cycloaddition reaction of a diene with a dieonphile to yield a cyclohexene.
|
Diels-Alder Cycloaddition reaction
|
|
|
The amount of heat released when a carbon-carbon bond is hydrogenated.
|
Heat of hydrogenation
|
|
|
A compound with alternating single and double bonds.
|
conjugated compound
|
|
|
An equilibrium reaction that yields the lowest-energy, most stable product.
|
thermodynamic control
|
|
|
A reaction that follows the lowest activation energy pathway is said to be kinetically controlled. The product is the most rapidly formed but is not necessarily the most stable.
|
Kinetic control
|
|
|
Allows the bonding electrons to be closer to more nuclei, thus leading to lower energy and greater stability.
|
Delocalization
|
|
|
When two reactions add together to give a cyclic product.
|
cycloaddition reaction
|
|
|
The product formed in a diels alder reaction.
|
endo product
|
|
|
Interaction between the pi orbitals of the double bond.
|
Stability of conjugated dienes
|
|
|
In the addition of HX to an alkene, the H attaches to the carbon with fewer alkyl substituents and the X attaches to the carbon with more alkyl substituents.
|
Markovnikov's rule
|
|
|
Longer wavelengths means...
|
lower energy
|
|
|
UV spectrocopy provides structural information about the extent of pi electron conjugation in organic molecules.
|
True
|
|
|
The energy difference between HOMO and LUMO decrease ...
|
when conjugation increases
