Which is the worst leaving group and why?
Cl- CH3COO- CH3O- HO- NH2-
Which is the worst leaving group and why? Cl- CH3COO- CH3O- HO- NH2-
which is a stronger base in water? Ch3O-, or Ch3COO-? A) CH3O-, because the negative charge is localized on the oxygen making the species less stable and therefore a better proton acceptor. B) CH3O-, because the negative charge Is de-localized on the oxygen, making the species more stable and therefore less likely to accept a proton. C) CH3COO-, because the negative charge is de-localized over the two oxygens, making the species more stable and therefore less likely to accept a...
