Ok so maybe someone can explain to me this. I think I may have it right but I want to check because I always get tripped up.

For carbonyls, if dealing with ketones and aldehydes, the reaction I need to think of is Acyl addition, with no leaving group.

For carboxylic acid derivatives, (Acid chlorides, anhydrides, esters, amides) I need to think Neucleophilic substitution, with a leaving group. But they can form enolates which can be a good nucleophile and add alpha.

As far as beta addition goes, I need to have a ketone or aldehyde with a conjugated double bond.

Here is what I do not know, when to tell if I will do an alpha hydrogen elimination vs carbonyl attack.

I do not know if I can make those assumptions but I always get them all mixed up. Sorry this is all over the place too, I just feel like I am missing the big picture with all this.
