UNZA pharmacist here ❤ Enjoying the chemistry

[@diyasoran8839]

who is else here is studying pharmacy and regretting it with his/her life ? 👋🏻

[@subconsciousmerchant4332]

Pharmacy is love 😒

[@aymenbourefis9146]

The struggle is real , tho , pharma forever 🙋🏻‍♂️❤️

[@atikamochi9760]

I'm not regret, 😂

[@abramsavantp.ybanez8302]

loving it so far org chem is currently my fav sub ♥

[@hiluti9482]

Here🤞😭😭😭

[@julie-du3fu]

You are an excellent teacher. Physical science is not my thing and you are explaining things perfectly to this biologist!

[@Duskydoc4259]

As a Neet Aspirant , this video is gorgeously knowledgeable 🌹❣️ Will now onwards watch ur video to grab more of the Organic Knowledge from u sir 🌹 Lots of Love from India🇮🇳

[@PunmasterSTP]

Did you already take the Neet, and if so, how'd it go?

[@priyamkamdar1056]

tf is "gorgeously" knowledgable bruh

[@FabiolaLopez-iy3if]

Thank you! Thank you! Thank you! Your videos are to the point and you explain things so well!

[@mekdesbelete8766]

you the giant organic person

[@PunmasterSTP]

Aromatic halogenation mechanism? More like "Amazing organic chemistry instruction!" Thanks again so much for making all these videos.

[@ambitiousbelmondo9219]

Awesome, say thanks will be never enough to show you how much you helped me , Thanks anyway

[@rominaniksirat5123]

Your videos are super super useful. Thanks!

[@morejacobmacholo4448]

Am a teacher student teacher sir and I wish you could be my mentor teacher ; you are perfect

[@lifelyrics5659]

Schools and lessons are god damn boring. It just Rob happiness

[@jesusmrosario-claudio4104]

Thank you once again.

[@BenardOnchieku-ny5qc]

Your naming is OK thanks

[@dylanzimmer2614]

Can you do one for Fluorination? Please!!

[@ishaankapil4982]

Flourination is not possible...

[@jameson1239]

The only real way to add a fluorine is by using HNO2 and HBF4 direct fluorinations are explosive

[@danielstacey2660]

Brilliant video, thank you

[@abirzonepro7962]

From Bangladesh ❤

[@ولاءمصطفى-ط1و]

Very good, thanks ❤️❤️

[@bw6329]

Amazing

[@puneetbhardwaj3869]

Ver well explained

[@ILoVeTheLioNKinG1]

How come for the first rxn with Bromination he didnt write the final product. Isnt it a benzene ring with with bromide attached plus FeBr3 plus HBr????

[@Lmanzo-Lion]

Thanks 👦🏻👍🏼

[@tom_winguill]

JG 🖤

[@mylight7856]

Thank you so much

[@Ash-rq1jw]

Amazing...you're amazing

[@saniyaidrisi]

Thannnxxx,, i really appreciate it

[@lalanto341]

What will happen if we use for example, HBr instead of Br2?

[@fatcammal]

you combust

[@MohamedOmar-z8b]

How would be the Iodination reaction if we use fecl3 instead of HNo3 (the oxidizing agent)؟

[@jvstRuee]

I’m waiting to see if we writing Cambridge

[@bignono2439]

Did you?

[@jvstRuee]

@@bignono2439 Yeah, we did

[@saamjamali8159]

Veeeeeeeeeeeeeryyyyyyyy useful

[@Qaiou]

thanks man

[@abichobaba-hm2ip]

10Q very much!

[@intanyustia1182]

Can we call this as the first mechanism of halogen?

[@paulharris2331]

Does anyone else think he kind of sounds like Mark Wahlberg?

[@PunmasterSTP]

Yes, I do too.

[@himanshuyadav4930]

Toluene + Br2/FeBr3 , Ortho or Para

[@sangurai3789]

Is the product of benzene + Br2 same as for Cl2 ( like HBr + Catalyst + main product)?

[@ismailmumin6724]

Is this reaction the same in all other aromatic compounds plz?

[@dishsoap5317]

Do you have videos on polybromination? Or ortho-meta-para directors?

[@jameson1239]

A bit late but a general rule is electron donators activate the Ortho and Para positions and electron withdrawing groups activate the Meta positions the only real exception is Halogens which activate the Ortho and Para positions while being electron withdrawing groups

[@erincostello5191]

How do you know which carbon on the benzene ring to add the bromine to?

[@tom_winguill]

any carbon

[@victorsahagun9997]

@@tom_winguill what if there are substituents on the ring? Or if two rings are connected

[@tom_winguill]

@@victorsahagun9997 as bromine is an electro negetive atom it selects the cabon with high electro positive character

[@ishaankapil4982]

@@victorsahagun9997Principle of directive influence will take place, if there is +I-Group, an electron donating group on benzene prior to Br, then due to resonance negative charge is created on ortho and para position of benzene and here Br is behaving like electrophile ( a positive chaged ion) and Br will attack on Ortho and Para Position of Benzene ring. And 1-bromo-2-nitro-benzene and 1-bromo-4-nitro-benzene is formed. And if their is a presence of negative-I Group like NO2, which is electron withdrawing group, created positive charge on Ortho and Para Position and as I said, here Br is behaving like electrophile not like electronegative atom, it will get repulsion from Ortho and Para position and attack on Meta position which is more electron rich as compared to Ortho and Para position, hence 1- Bromo-3-nitro- Benzene is formed.

[@ishaankapil4982]

@@tom_winguill No here Br is behaving like electrophile a positive charged ion, electronegativity of Br is seen when it is bonded with some other element than Br itself...

[@yourfavouritescepticx8969]

I don’t understand the step where the Nucleophile ( the aromatic ring ) attacks the Electrophile ( Cl +). Why does the second carbon that forms the pi bond get the carbocation charge ? Help me please I’m slow I’m learning but this is very interesting. Chemistry might just be my favourite science

[@VenuGopal-js1qu]

there the c atom has 3 valencies occupied,but being tetravalent it gets a + charge as the c atom above it gets chlorine so it breaks the pi bond with lower c atom

[@matysetthem7783]

Wait who are you?

[@POIPOI-ws8kt]

is it usable on toluene？

[@BenardOnchieku-ny5qc]

Why is the compound unstable

[@rahasworld]

Why is iodination far simpler than the other two? It's as if a solvent isn't used

[@eishi25]

yawa wala gihapon ko kasabot

[@abramsavantp.ybanez8302]

balik balikaa HAHAHAHAH

[@goldfishanouar]

In iodination, what's the role of the acid H2SO4??

[@tom_winguill]

catalyst

[@rockypop9506]

Yea catalyst

[@Saujas]

This cyclic compund isn't activated And u didn't explain the reversibility part of iodination Waste of time
