what is the relationship between the leaving groups and the attacking base?
|
anti and the two carbon centers are all in a plane
|
|
can E2 occur by syn periplanar transition
|
yes, could happen in rigid structure incapable of achieving the more favorable anti-periplanar conformation
|
|
syn periplanar has what kind of strain
|
unfavorable torsional strain
|
|
does attacking group attack axial or equatorial H
|
axial
|
|
leaving group must be axial or equatorial
|
axial
|
|
what is another name for a non zaitsev product
|
hoffman product
|
|
what can provide stabilization of the system
|
hyperconjugation due to overlapping between different orbitals
|
|
define resonance
|
movement of electrons in orbitals via conjugation
|
|
when does a 1,2 hydride shift take place
|
wheever they can produce4 equal or greater stability of carbocation
|
|
define hydride shift
|
you move H and its electrons to the next carbon
|
|
which is most stable
