To identify which compound is more acidic in a given set of compounds. Concept introduction: Keto-enol isomerization is possible when a keto group present in the compound has a movable hydrogen atom in the next carbon attached to the carbonyl group. This occurs generally in almost all keto compounds where a chemical equilibria is present between the keto and enol form of the compound. Conversion of keto to its enol form is known as keto-enol tautomerisation. If the formed enolate (conjugate base) is stabilized by delocalization of the charge and if the hydrogen that is going to be removed are surrounded by more electron withdrawing groups then that compound is said to be more acidic.

Don't used Ai solution

I have a question about this problem involving mechanisms and drawing curved arrows for acids and bases. I know we need to identify the nucleophile and electrophile, but are there different types of reactions? For instance, what about Grignard reagents and other types that I might not be familiar with? Can you help me with this? I want to identify the names of the mechanisms for problems 1-14, such as Gilman reagents and others. Are they all the same? Also, could you rewrite it so I can better understand? The handwriting is pretty cluttered. Additionally, I need to label the nucleophile and electrophile, but my main concern is whether those reactions differ, like the "Brønsted-Lowry acid-base mechanism, Lewis acid-base mechanism, acid-catalyzed mechanisms, acid-catalyzed reactions, base-catalyzed reactions, nucleophilic substitution mechanisms (SN1 and SN2), elimination reactions (E1 and E2), organometallic mechanisms, and so forth."
