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
1.) sp2 hybridized
2.) no hybridization no ring
3.) ring
sp2 then ring then none
which occurs if both 1,2 hydride and 1,2 methide are possible?
1,2 hydride
