Here's one more trick.....if the central atom of the attached group has a lone pair it is ortho para directing but if it has a pi bond then it is a meta directing 😅 hope it helps 😊

Thank You so much for your much appreciated feedback! I am so glad this helped in a shorter amount of time!

I have my final exam this week for Organic Chemistry II, and this saved me . I usually need a reason why things happen in order to learn them correctly or for it to stick, and this clicked for me pretty fast! Certainly easier to remember than 15+ substituents.

How can we then rank them to each other? Do we have to memorize it then?

@PraxisAcademic

Жыл бұрын

The more electronegative a substituent is, the more of an inductive effect it will have, meaning the more powerful it is as an electron-withdrawing group and the more likely it will be to determine where another substituent will substitute on to the benzene ring. So, rank them among each other based on electronegativity/inductive effect. For example, a -NO2 (nitro) has a greater electronegativity and inductive effect than a -COOH group, because even though both have two oxygens, nitrogen is more electronegative than carbon. For another example involving electron-donating groups, an -OH group versus a -NH2 group, the -OH group is more electronegative than the -NH2 group because oxygen is more electronegative and there’s only one H on the oxygen versus two on the nitrogen. Also, know that if there are already two substituents on a benzene ring-one more electronegative than the other OR one electron-withdrawing and the other electron-donating-substitute a third group meta to the more electronegative substituent OR meta to the electron-withdrawing group. For example, in the case of -OH versus -NH2 whereby -OH is more electronegative than -NH2, the -OH will have a greater electron-withdrawing inductive effect causing meta attachment from -OH of a third substituent. I hope this addresses your question and helps!

Great video. But I have a question, NH3 is considered deactivating and NH2 is considered activating. But why is that since the Nitrogen is more electronegative than the hydrogens?

@PraxisAcademic

9 ай бұрын

First--thank you! Second--excellent question! When an NH3 group is attached to the benzene ring, it will obtain a formal positive charge (N with 4 bonds is positive 1 charged) and is void of lone pairs (void of e-, essentially)); the positively charged N will then be super attractive to electrons, drawing electrons toward it, withdrawing electrons away from the ring (EWG, meta-directing, deactivating); in this case the positive charge on the N outweighs the effect of the electron donating groups attached to the N (this is even true for NR3+ groups). Formal charges are powerful! When an NH2 is attached to the ring, it'll only have 3 bonds keeping it at zero charge, maintaining its lone pair and usual electronegativity to pull electrons away from the Hs, become "electron-rich", and donate electrons to the ring.

@PraxisAcademic

9 ай бұрын

To help make this more clear, it helps to think about NH2 to NH- groups attached, both are electron-donating-groups and both are activating, but the NH- groups is a stronger activator because it has a -1 charge and is more electron rich, so it donates electrons to the ring.

@PraxisAcademic

9 ай бұрын

It's like the OH and O- groups; both are electron-donating-groups and activating.

@PraxisAcademic

9 ай бұрын

So, simply think of a group whereby if the alpha atom [to the ring] is negative, it will be electron-rich and donate to the ring. And a group whereby if the alpha atom [to the ring] is positive, it will be void of electrons and withdraw from the ring. Kind of like if you have no cash on you, you withdraw cash from the bank.
