Post by: aspiringphysician on September 05, 2013, 01:50:13 PM
Why is a carboxylic acid a stronger deactivator (i.e. more electron-withdrawing) than an ester?

Can you explain to us why either acids or esters are deactivators first of all?

I.e. what mechanism makes them deactivate an aromatic ring.
