...group is week ring deactivator but Ortho and para director​

Answer»

It’s one thing to learn about electrophilic aromatic substitution reactions of benzene itself. But once you MOVE beyond benzene, that’s when things start getting really interesting.Today we’ll describe the two main patterns by which substituents “direct” electrophilic aromatic substitution. In one pattern, substituents direct the REACTION to GIVE EITHER the “ortho” (1,2) or “para” product, with a slight preference for “para” (1,4). In the second pattern, a different family of substituents direct the reaction to give primarily the “meta” (1,3) product.Table of Contents ortho-, para- Directorsmeta- DirectorsHow WELL Do “ortho-, para” And “meta“- Directors Correlate With “Activating” and “Deactivating” Groups?The Key To Understanding ortho-, para- Directors And meta- Directors Is To Understand The Stability of The Carbocation Intermediate
