Homework Answers
(a) In quinine antimalarial
drug structure number 2 nitrogen atom is more basic because the
lone pair of this atom are not going into resonance with benzene
ring and hence make it more basic.
(b) Number 1 nitrogen atom is more basic due to the presence of lone pair on N which doesn't tie up in resonance with double bond.
In tacrine structure the number 2 nitrogen is less basic because the lone pair on N is in resonance with benzene ring.
