How to pronounce“anhydrides”in English

Our acid chlorides, anhydrides, and esters can all be transformed into this group.

We worked around this by making carboxylic acids into more reactive derivatives, like acid chlorides, anhydrides, or esters.

Because we can reduce the less-reactive esters, amides, and even carboxylic acids, we rarely bother to make more reactive compounds like acid chlorides and anhydrides to do these reactions.
