Acid Chlorides, Anhydrides,
Amides & Amines

What are four derivatives of carboxylic acids, i.e. acyl compounds?

The four acyl compounds (acid derivatives):

What are acyl chlorides?

Acyl chlorides are the most reactive derivatives of carboxylic acids, and they have a general molecular formula of :

What are acid anhydrides?

The 2 $^{nd}$ most reactive derivative of carboxylic acids which has a general molecular formula of $(RCO)_{2}O$ :

What are esters?

The 3 $^{rd}$ most reactive derivative of carboxylic acids which has a general molecular formula of $RCO_{2}R'$ aka :
