Ortho Meta Para Directors - Activating and Deactivating Groups

This organic chemistry video tutorial provides a basic introduction into ortho meta and para directors. It discusses the reactivity and directing effects of strong activating groups, moderately activating groups, weakly activating groups, weakly deactivating groups, moderately deactivating groups, and strongly deactivating groups.

    hey man, at roughly 3:15 you say these groups are moderately activated and then you say they are ortho para. Then at roughly 13:00 you say moderately deactivated prefer meta. However the molecules look veryyyy similar. Can you explain?

  • @nicoletteschiavone5980

    @nicoletteschiavone5980

    5 жыл бұрын

    It's all depends on which atom is bonded to the benzene. The ester at 3:15 has the oxygen directly bonded to the benzene ring, thus it is a moderately activating group because oxygen has a lone pair and can donate electrons to the ring by resonance. The ester at 13:00 has the carbonyl carbon bonded to the benzene ring, NOT the oxygen, thus it is a moderately deactivating group because the carbonyl carbon has a partial positive charge and withdraws electrons by resonance.

    Just remember this. Lone pairs - activators and o/p directors. Double bonds mean deactivators and meta directors. Halogens are also deactivators that o/p direct but they are an exception.
