Can an Electron Withdrawing Group(EWG)(like NO2, F, Cl, OH, etc.) behave as a Electron Donating group(EDG) in a compound where a carbocation is present in order to stabilise it?
Does the position where it is present or distance from the carbocation affect it's behaviour as an EWG or EDG?
I feel that it should behave as an EDG as carbocation is electron deficient so it has a greater tendency to accept an electron.
Can we say a similar thing that an EDG behaves as an EWG in presence of carbanion as it has excess electrons?
