WebAcidic conditions speed up the reaction because the protonated carbonyl is more electrophilic. Under Basic conditions 1) Nucleophilic attack by hydroxide 2) Protonation of the alkoxide Under Acidic conditions 1) Protonation of the carbonyl 2) Nucleophilic attack by water 3) Deprotonation Problems WebMar 7, 2024 · The carbonyl group provides a site for nucleophilic addition (also known as nucleophilic attack) and increases the acidity of the hydrogen atoms attached to alpha carbon. These two effects are consistent with the structure of the carbonyl groups and are due to the ability of oxygen to incorporate a negative charge. WebJul 25, 2014 · As the positively-polarized carbonyl reacts with (forms a bond with) the nucleophile we pass over a transition state and fall into a second potential well representing the tetrahedral intermediate.
