Default stability of carbokation(?) as in SN1 Reactions




The order of stability would be from the least stable to most stable:
2,3,1

Since all are endothermic reactions, the transition state should
resemble the products of the reaction, the carbocation.

2 would be the least stable since it is highly unfavorable to form a
carbocation with an electronegative element in close proximity.

3 will be stabilized by electron releasing groups in near proximity, a
small scale delocalization of electrons.

1 would be most stable since the carbocation formed will be
effectively stabilized through resonance...delocalization of its
electrons.
