(1 ) Draw complete reaction schemes and mechanisms for the two reactions of sodium Saccharin O-ETHYL SACCHARINE and N-ETHYL SACCHARINE with Iodoethane.
(2) Predict the approximate chemical shift of the proton resonance signals that you would expect to be most different in the two product.
(3) which proton do those signals correspond to?
