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.Sulphur is more nucleophilic than oxygen
Hint : Less electronegativity
But
Ye
Jude kyun
u do realise reagent is a carbene right
Yes
But
Mai kuch miss krra hu
S ke khali orbital
mein c ke electron gye
+ve aaya
O ne apne de die
just my thought process
do confirm from enamine sir
But
Ye thought answer dekhke aaya kya?
Agar mujhe pata nahi hota kuch
Fir kya sochta
Carbene kahan se aaya ji
Ye nucleophilic addition hai
Tum dekh paa rahe ho
Ki C=O hai
And doosri species me lone pairs hain
Which make them nucleophilic or vo C=O ko attack karenge
Now the question is
Kya dono OH attack karenge
Ya ek SH ek OH
Ab dono OH se better ek SH or ek OH isiliye hai kyunki S ka lone pair jyada available hai
(less electronegative)
Baaki full mechanism dekhni hai to look up "protection of aldehydes and ketones using diols"
this
oh shit am blind dikha hi nahi
C=O
mb
if it were carbene then it would work right??
C=O hai yaar ðŸ˜
Carbene ko react karne ke liye dono chizein chahiye
shouldnt O ka lp attack first
Pair of electrons or fir lack of electrons when they are removed
S ka karega imo
S is more nucleophilic
Sulphur ka khali orbital hai toh carbon ke electron bhejne ke lie
Banayo fir kya banayoge
What would be the fashion in which you attack?
S ke electron are relatively more stable since the atom has a large size . oxygen relatively chota hai so jaldi attack kardenge
sendin
How are S ke electrons more stable
What do we exactly mean by stable in fact
d electrons aaye nahi abhi
To poora shielding nahi hai
S me net effective nuclear charge kam ho gaya in fact
Outermost electrons pe
S less electronegative hai isiliye uske lone pairs would be more available is what I believe
Agar tumhare vaale logic se jaayein to fir dono hi oxygen attack karne chahiye
Line ke neeche wala dekho
arey han yeh toh socha hi nahi
HANN
kinda feels wrong now due to all the charges ngl
S ka hydrogen kahan gaya
whi toh gadbad hai
See aise hawa me nahi ho jaati chizein na ðŸ˜
And maybe I'll look over thinking how a Carbene could react to this thing
It's in Clayden btw
On how Carbenes react with alcohols and stuff
Maine apni report me bhi likha tha 🙂
acha
meine kabhi padhi nahi carbene rxns
so..
Padhi hain indirectly
only in phenols
Still
Alkenes ki bhi to padhi hain in general
Simmons Smith vagahra padhi hai?
Nahi?
nope
Hmm fir to phenol vaali hi hai
Simonin pata ha
😎
Chal samajh gya convo jo bhi hui
simonini han
Bhai hardcore yar
Vo integration vala dekhlio yar
Ye konsi bala hai
3rd one
Jisme I lag jata ha
Ester banta ha
I don't remember tbh kiski baat kar rahe
try karta hu
