5 CHEMICAL REACTIONS OF PHENOL | AROMATIC COMPOUNDS | CLASS 12 | JEE MAIN | IIT ADVANCED

[@harivatsaparameshwaran4174]

Sir conversions karna bekar nahi tha , bahut sikhne ko mila , syllabus cover hone ke bad , agar apke pas samay hai to conversions ka 2-3 videos aur bana dijiye. Thank you sir.

[@Kirti-ub8zy]

16:53 for those who are thinking why we are using bromination ,not using chlorination again ; because chlorine will attack on Ortho position note on para position because of a small size

[@NaivaidyaKaushik]

But fir 3 question me consecutively cl2 alcl3 kyu use nahi Kiya?? please tell

[@integration_IIT_ISM]

23:00
Mononitration-->bromination-->reduction of nitro to Nh2 -->diazotisation-->sandmeyer reaction

[@tanis_ltd2081]

Sir in 21:56 we can do sulphonation rather than doing nitration as we can remove SO3H in just one step.

[@sarthakkhatale]

IPSO attack will happen and HSO3 will be removed by chlorine itself

[@AK-vb9ks]

21:20
Aise kar sakte hay kya
First chlorination
Then sulphonation ( para me SO3H lgega)
Then bromination ( Cl ke ortho me Br lgega).
Then desulphonation ( SO3H hat jyega)
Then Mg + dry ether
Then di grignard reagent se O2 and hydrolysis krke final product

[@ks33390]

6th 1) sn hcl 2) kno2 + hcl 3 ) heat + c2h5cl alcl3 4 hcn + cucn 4) h3o + heat.

[@hemadrisingh1362]

Actually nh2 is an activating group, it won't show friedel craft alkylation, try converting nh2 to nhcoch3 and then proceed to do the alkylation

[@arindamkashyap9420]

These interconversion questions were really helpful sir! They were all like summaries of orm 2, some reduction, and this chapter

[@sirajahmed5402]

to form hydroquinone and catechol we can simply do 1) phenol formation using v2o5 ,,,,, and then 2) Elbs rxn

[@ks33390]

5 th 1) cl2+alcl3 2) mg +ether 3) co2 (orm 1) 4 c2h5cl alcl3

[@FlakernN]

Very nice solution

[@sagnikghosh4980]

Bro iit mili terko?

[@kunalmandal2199]

Excellent lecture sir

[@mydearfriend007]

54:46 less hindered alcohol

[@atharvbajpai8127]

38:25 sir carbonic acid kuch extent me to banta hoga aur le chatelier principle se to co2 aur h20 me convert hone par equilibrium forward shift hona chahiye

[@kushagragupta3416]

obviously

[@ShivDixit-i4j]

Sir 27:40 par apka soln me zn amalgum in presence of hcl no2 ko nh2 me convert kar dega diazotization ki jarurat hi nhi thi

[@_.prettyxblithesome]

Sir 21:27 me di grignard reagent nahi banta hai benzyne mechanism me do benzene ring se jud jayenge

[@imPriyansh77]

Benzene to hydroquinone can also be prepared by :
Chlorination of benzene gives chlorobenzene . Further chlorination of chlorobenzene gives major product as p-chloro chlorobenzene . Applying Dow's Process to p-chloro chlorobenzene , hydroquinone can be made .(benzyne mechanism)
SIR PLEASE CHECK THIS METHOD!!!🙏🙏

[@xywc9188]

2 video in day thnks sor

[@FlakernN]

For 5th interconversion, can we do this?:
[Benzene] > V205 (300°C) > Sulphonation > rex with XMg-COOH > Zn dust+∆ > CH3-CH2-Cl + AlCl3

[@bharatiyainnovator3185]

7:23 zenith reaction

[@nishchaykumar6942]

13:00 acetanillide qn came in jee m 2021

[@alphaiitd1]

Thanks sir

[@shiken69420]

It was a good revision of orm2, and the first 4 vids of this chapter

[@shivam_IIT_RPR]

Sir P isomer me two times chlorination krwa kr dow's method se bn jata

[@rekhamishra2000]

Yes maine same yahi kiya

[@rohanbeniwal9241]

2 video in a day 😃😃😃😃

[@gitakumari2166]

Sir first Fenton's and then elps persulpgare reactions

[@bimalgayali1359]

Thanks

[@sauravsingh580]

Tq sir

[@DJ-ki5dr_]

47:15 sir yaha SN2’ reaction nahi hoga?

[@atharvamehta987]

The mechanism followed is SN2 only.

[@sharmaambika8454]

Agar hum do molecule V2O5, 300°C pe le tooo hydroquinone banega kya aur nahi to fr q?

[@lakshya3199]

56:40

[@hopesalive2004]

sir, phenoxide me steric hindrance ortho position pr km kese ho skta h compared to para ? can u pls tell ?

[@XXXXXX-w6v]

FOR CATECHOL WHY NOT JUST NITRATE TWICE THEN REDUCE THEN DIAZO?

[@existential_turtle]

The NH2 would be in ortho position of the other NH2, in which case it wouldn't undergo diazotization.

[@khanakhao207]

thanks sir

[@VladimirPutinIITian]

nice name.....reminds me of mom
