i kinda got how it went to how to form the cn part but when the strng base is added in getting stuck there as to what the mech will be

@Dexter
Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.Base hydrogen lega
Benzylic position se
'cause you have an electron with drawing group there
As well as resonance
Then nucleophile ban gaya
It attacks on C6H5-CHO
C=O ko khol dega
Attaches there usse aage dekh lo
Hydrolysis hai to cyanide ka carboxylic acid ban jayega
And O- ka OH ban jayega
Then you add SOCl2
To COOH ka COCl
And OH ki jagah Cl
Then amine attacks and removes Cl
I'll draw it out jab pen paper hua
Abhi ke liye isse dekho samajh aa raha hai to
Ohh ek second
I didn't realise one thing
C6H5-CHO vaale step me heating bhi hai
bich ka ik c kaha gya?
acha ye reagent wala hai
ok
Konsa bich ka?
Yeah
To elimination bhi hogi
I'll send draw karke
This is a good one
@hardcoreisdead dekhna ye vala
It's a really good one for your practice too
hnn
basically second step changed CN to carboxy right?
Yeah yeah
ok ok
and then carboxy is protonated?
what
or is it cooh after protonation
Anything that has negative gets protonated
And jahan hydrolysis possible hai that gets hydrolysed
Is case me it will form cinnamic acid kind of a thing
to the C=O is protonated?
Abhi nikal raha draw karke better bata paaunga ðŸ˜
lmfao read the last one
Yeah it would but usse aage kuch nahi hoga
the yeild
Wow
to usko karne ka kya fyda
So nice
75% yeild of wurtz
Fayda kuch nahi hai
Ho jayega yes ye bol sakte ho
Just jee things
Ya neet
Whatever
to basically yaha di ol hoga ? or am i going spirales again
Naah naah
I'll send wait
hnn
I'd say move ahead
Mai bhejta hun jaake
47th bhi
hnn
Vo bhi dekh lunga koi ni
oxidation part is getting me like what
okkk
It does I get it
yhh
Ye lo
Doubts aayenge kaafi
Pooch lo jitne bhi hon
This is not haloalkanes ka simple question at all
wait there is litral shift and additon of ph here?
Naa naa
or is it that both the componds get bonded
It's just a nucleophilie attacking the C=O of the aldehyde
The initial cyanide thing gets deprotonated
Forms a nucleophile
It can attack nothing but the most electrophilic thing around it
The aldehyde!
so the inital one we had attacks the o in aldehyde
and they both form a bond
Naah
The the Carbon of C=O
Not O
Carbon has partial positive right?
C=O bond is polar towards oxygen
Carbon se pull kar raha hai oxygen
aa okk okkk i was getting confused in structure
Dw
See it carefully
This is kinda weird
Or answer bhi confirm kar lo btw
how the reagent and they halocyanide is getting bonded
I think it should be correct
ni diya
school level ke nhi rhte is book me
Halocyanide?
Ye school level hai?
💀
kya likh rhi hu mai
cn compound with aryl grp
See
Base tha
Usne proton liya
Negative reh gaya
Gets stabilised by cyanide ka -M
And phenyl ka -M and -I
So negative aana is favoured
resonating structure bhi hoga hnn
Then that negative is a nucleophile
It attacks the most electrophilic thing in the solution
the aldehyde
yh
Yes
That as the double bond if formed is very conjugated
And there is heating involved as well
To elimination hogi
This is by "E1CB Mechanism"
ok ye kuch naya hai
Aldol me hoti hai jo
You'll see it in aldehydes and ketones
Vahin pe first time introduce karte hain
How are these people so dumb yahan kyun hai ye question ðŸ˜
This question doesn't belong in haloalkanes and haloarenes
Saare concepts aldehydes ketones vaale hain
aakash
🤡
that too it is given in school section
thoda baht smj aaaya ik var mai mech se karke dekhti
Koi ni dw
Iske liye concerned mat hona
Ise note kar lo
Question accha hai
Aldehydes ketones hone ke baad dekhna
Easy lagega
Just weird
Why do you wanna torture kids ðŸ˜
Mai ro deta pehli baar haloalkanes karte time dekhta to
okk
maine pehli vaar me ignore maar diya tha
iska batana
merko stero abhi kar lena chiye ya baad me? alc ke aas paas?
47th na?
Kar raha hun wait
Stereo padh lo
Victor organic se padh lo
Accha padhaya hai
hn
You’ll get your basics really good
ok ok mai nikalti lec
Mai bhejta hun dm ruko
Saare nahi dekhne
okk ok
Pehle 47th dekhun
hn vo
Yaar ye bhi aldehydes ketones ka hai ðŸ˜
Dekh lo
You most likely won’t get a lot of it
I’ll try explaining but it’s difficult
...tabhi
Dw about these
Ye sab questions are made thinking tumne sab padh rakha hai
last step chood ke kuch smj nhi aaya
Dw
Abhi note kar lo
Questions acche hain
Just Abhi tumhe aata hi nahi ye
Reactions hi nahi pata
mai iska ans note kar leti hu
Mere solution ko chhaap lo exact
Bas answer mat likhna
hnn vaise bhi bgl vale page me likha
udhr jagh nhi hai
Hmm kar lo bas ye yaad rakhna ki aise questions hone chahiye tumse
hnn
