You're right. But to be more accurate, we can say 2p-2p overlap is more effective than 2p-3p. Effective overlap is better term than calling them stable or less stable
Mam, please increase frequency of carruthers series...it is very very useful..and your teaching is owesome...plz mam upload carruthers series regularly ..plz..🙏
Ma'am good morning ,I have one question. Carbocation is planer but carbanion is pyramidal in shape and how can we exchange the two groups by keeping the PPh3 group in the same downward position.If suppose carbanion is planer we can exchange the two groups by keeping PPh3 grp. in the downward position by flipping,but the main case is it is pyramidal in shape.Please reply ma'am,I m waiting.❤️🙏🙏🙏🙏
in NPh3 there is 2p-2p overlap of C and N. hence lonepair of N is not available for the attack. in PPh3 there is 2p-3p overlap of C and N, where overlap will be of less extent, hence PPh3 attacks not NPh3.
Hello mam, phosphorous ylide me pph3 or nph3 me difference ye he ki n or c both is 2p-2p overlapping so lone pair of nitrogen used in conjunction or phosphorous is 3p orbital iss liye unke lone pair donation k liye available hote he.
I hv completed all the videos of carruthers series...i tried to solve all the reactions in this series on my own by pausing the videos time to time..and i m happy to share that most of the reactions i solved very easily just because of your hydrogen batch which i had joined...tumne itne achche se sab karaaya hua hai app mei ki ab tak yaad hai..( missing those days of app..jab har roz naye video ka intezaar rahta tha) organic ka o bhi nhi aata tha mujhe ( haalanki ye galatfahmi thi ki bdi achchi organic hai meri🤣🤣) par ab organic ke a tak to pahunch hi gyi hoon..c tak pahuncna chahti hoon .isliye pls aur videos upload karna is series ke, jab bhi tumhe time mile( because ye dil maange more😁),tumse achcha aur koi nhi padhaata. I m surprised to see ki kuch gadhe aise bhi hai jinhone videos ko dislike bhi kiya hua hai ..arey bhaiya ab jaan loge kya ladki ki...sab kuch itne achche se explain kiya to hai...Bahut saare you tube channel search kiye...but kuch mza sa nhi aaya...tum yaad kara deti ho sab kuch ..har cheez ka reason deti ho tum.aisa koi aur nhi karta ya ye kah lo ki mujhe samjh nhi aata....bus humesha aise hi rahna..aise hi sabki help karte rahna...bhagwaan tumhe khoob khush rakhe .saari ichchayein poori ho tumhaari ..may you live long ❤❤
Yes, in that video, I was considering that you're following Clayden and Carruthers both in your preparation. Like I had said to do pericyclic from Clayden, because the language of that book is easy and proper mechanisms are given. So for students who are self-preparing, Clayden should be the preference. Same is with Enolates, it's easier to do from Clayden.... Carruthers mein mechanism hi nahi given, but if you now see the videos of Carruthers Chapter 1, I've explained each reaction with its mechanism....so aap yahaan se bhi kar sakte hain
Mam jese aap yh videos dalte ho, or aapke individual course k packages bhi hai , suppose we've bought organic only , will all these topics be covered under them or we should watch your TH-cam series separately?
In :PPh³ their is empty d orbital so it easily give SN² reaction easily In case of :NPh³ d orbital is empty so SN² reaction is not possible ond N-Ylide is not formed
Mam...if I join lockdown batch on J chemistry app then the videos avaliable on it contain full syllabus of CSIR NET... OR together I've to follow other study material also❓❓
Pph3 donate it's lp because of phosphorus which is attached to c is 3p 2p overlapping not possible so this is available for donations but In nitrogen 2p 2p overlapping is possible to delocalized in benzene ring
The word umpolung means "reverse of polarity".. suppose you have any organometallic reagents such as Ch3MgBr..here Carbon contain partially negative charge and metal contain partially Positive charge.. But we know carbon usually contain partially postive charge (CH3Br+ Mg in ether = CH3MgBR )..in reactant carbon contain partially postive charge but in product the polarity is reversed..this phenomenon is known as umpolung or reverse of polarity
In wittig reaction,, if the phosphorus ylide is stabilised by sp3 hybridized group like CF3 , then the stabilising group will be non planar and steric interaction with ch3 group will take place. In this case which isomer will be formed, z- and E-?? Please explain
Ma'am ap mujhe bata sakte ho kab mein NET exam k liye eligible hongi( matlab mein konse yr mein de sakti hu 2022 Dec or 2023 June)... Agle sal mera BSc complete hoga
J chemistry mam ..I watched almost all your videos ..I have done M.sc chemistry from Lucknow University and then completed two year diploma I.e B.ed ...I want to teach as like you but not at jrf net level ..I want to teach 11and 12 full ncert based plus how to connect academic content to neet level for medical student ..I also have specified in organic chemistry .... ......can you suggest me what should I do because family want government job and there are other issues also .I am stuck between these conflict .....still in dillema
Ma'am could you pls tell that from where we can practise the questions of organic? In clayden only few solves questions are given which are insufficient
Mam,next video kab ayega? Plz mam increase frequency of carruthers video.. these are very very useful..mam many many thanks for starting carruthers video series...plz mam upload next video...🙏
Mam mane abhi abhi test series join ki h and ek test bhi diya h but after watching solution video I have one doubt so mam from where I got doubt facility number?
Mam it's too hard for me to deal with physical chemistry ..I attempt your GPC first assignment but solve only 6 q ..how i can build my interests in phy.chem.it's too hard for me 😔
I have a request , aap explain systematically krtein kafi ache se but mam jb aap written krte mam use b sequential rkhiye . Bcoz hum jbi copy krtein bahut hi prblm ho jaati. Aap usi m sb kuch explain krdete or fir erase. Tou bahut se step humse miss ho jaate baad m pdhne ya revision mei kaafi dikkt aati ek b step miss ho jae
Mam you're so knowledgeable but improve your teaching teqnique, just go step wise so we can understand it easily. I'm skipped video just because of messy things of board.
Teachers are the probably the only people who use almost everything they learned in school almost everyday...
:PPh3 has 2p-3p overlap, less stable, more reactive.
:NPh3 has 2p-2p overlap, more stable, less reactive
You're right. But to be more accurate, we can say 2p-2p overlap is more effective than 2p-3p.
Effective overlap is better term than calling them stable or less stable
@@JChemistry yes mam. I got it. Thanks 🙂
Di ye bhi to bol skte h ki nitrogen more electronegative hence less donor
@@shashanktripathi8849 no bo higher is the electonegativity lower is the its necleophilicity....
Lone pair present on the nitrogen atom resonance with benzene..so nitrogen can not donate it's lone pair....2p_2p interaction....

I did not get it. Could you repeat in more detail?
Size ka khela heh .....like P ka size more than N ,so room jadah hoga orbital meh so p bazizhak apna lp dega EN kh through se bhi dekh sakteh heh ...
Thank you so much ma'am......miss your awesome board....
You'll see that soon :)
I think that N have no d-orbital so if the ph3N attack on C then the reaction is not prossidior.. After the SN1 reaction the SN2 do not prossidior
Very nicely explained mam..love from Pakistan
Maam N (ph)3 me effective conjugation hongi ph ke sath than P(ph) 3 so lp is not that available for attack on methyl gp

In stable form , both E and Z should be possible as there is no hindrance in both. Then why only E form obtained?
21:10
Bro mostly EWG jo hai wo stablised ylide banata hai whi trans alkene bhi banata hai
Thats why nitrogen lone pair not attack on ch3 it delocalized on the benzene ring
N Can't extend its configuration, absence of d orbital
Mam ap jo question puche why phosphorous qnd why not nitrogen? It can also be explained using HSAB principle
Mam do you have any course for iit jam 2022
Hii mam..Kya aap set exam for chemical science preparation strategy video bana sakte ho? Plz it's request
Very nice explanation mam👍
Or agar maam N attack karke ylide bana b le vo bahut unstable honga due to absence of d orbital
Which boards are better white boards or chalk boards??
Hi mam, miss seeing your face, hope you're doing well ❤️
You'll see that soon 💚

Why witting reaction should be perform in dry and inert condition..?
In :PPh³ their is empty d orbital so it easily give SN² reaction easily
In case of :NPh³ d orbital is empty so SN² reaction is not possible ond N-Ylide is not formed
No
Mam regularly uploaded karo mam pls a series sab complete karo mam...your lectures are awesome mam
