How does (i) an electron with drawing group (EWG) and (ii) an electron donating group (EDG) influence the acid strength of carboxylic end? |
|
Answer» The electron withdrawing group stabilizes the RCOO- and strengthens the ACID. They are usually happens at para/ortho place of an electrophilic substitution LIKE aromatics compounds. ii) The electron donating group stabilizes the RCOO- and weakens the acid. It resonates the aromatic ring by forming a resonate electron density. iii) The influence of the INDUCTIVE effect on acidity is UNDERSTOOD in TERMS of conjugate base RCOO- from the above explanation. |
