describe hybridisation in an e- poor aromatic
describe hybrisisation in an e- rich aromatic
e- rich so 2e- in the p orbital so the lone pair can be conjugated
e- rich can add electrophile where
add in C2 or C3,, any carbon is the same but we lows prefer C2 bc theres more resonance structures for it
it = the + charge
e- poor can add an electrophile where
on C3,, bc the + will then be on the C and not the N,, and N is an EWG so we dont want it to be positive.
indole,, where do we want the electrophile added
lowks C3 or C2,, we dont want to break aromaticity.
N is pyridine is what directing
METAAAA
an OMe in pyridine is what directing
