is a double bond more electron dense than c=o

what makes you say this? O is more electro-ve na. this isthe main reason behind all ald and ketone rxns at the C=O bond so the electron density will be on the O, and will be higher there

i had the same reasoning mcpba is supposed to attack on more electron dense site so D banta but C is correct anyone..?

m-cpba did epoxidation of double bond if I'm not mistaken. (Idk the reason, this was just written in my notes ;_;)
CorrodedCoffin
CorrodedCoffinOP•3mo ago
yeah but why not the c=o

Heyy @hardcoreisdead I feel like it’s more about the product being formed In the case where you got both ketone and C=C The C=C forms a product with a relatively higher energy strained But the Baeyer villiger oxidation leads to a six membered ring which is to say the least strain free So I think the answer should be ABD https://chemistry.stackexchange.com/questions/134495/m-cpba-selectivity-between-baeyer-villiger-oxidation-and-epoxidation I found something Ngl though I’ve never encountered such a thing The answer seems to say that it depends

u r the one whos supposed to ans

I didn’t check A and B ngl I thought they were clear enough Baeyer villiger hogi
CorrodedCoffin
CorrodedCoffinOP•3mo ago
B is wrong lol
Varun_Arora
Varun_Arora•3mo ago
Then it’s about selectivity I’m each Hoga I didn’t check as I said Mujhe laga vo to apparent hoga like Structure me kuch galti ki ho to alag baat hai Reaction was clear ki ko si hogi That’s why just checked C and D
CorrodedCoffin
CorrodedCoffinOP•3mo ago
A is def correct since more electon dense site pe rxn hoti B is another story
Varun_Arora
Varun_Arora•3mo ago
B me kya issue hai check karta hun
CorrodedCoffin
CorrodedCoffinOP•3mo ago
C and D mein bhi electron density ka relation hai
Varun_Arora
Varun_Arora•3mo ago
Ohhhh Bridgehead
CorrodedCoffin
CorrodedCoffinOP•3mo ago
can we say red is more electron dense than green due to electrong withdrawing nature of c=o

I guess aise hona chahiye B? @hardcoreisdead

@hardcoreisdead Inductive to vaise hi 3 carbons ke baad doesn’t affect much So can’t really comment if it would relatively affect much here Dono ki apni almost independent electron density hogi Depend karega situation pe ki kya hone vala hai As that stack exchange vala answer said

CorrodedCoffinOP•3mo ago
yep then why is ans AC 😭
Varun_Arora
Varun_Arora•3mo ago
Haan to sahi to feel ho Raha hai 6 membered ring Ohh nahi Wait wait

oohh tab alag baat hai PADHAI KARO JAAKE
Varun_Arora
Varun_Arora•3mo ago
Padhai nahi majdoori Aaj vaise hua yaar kaam thoda thoda Didi bechaari presentation me busy hain apni 😭 @hardcoreisdead tum bhi padho ye if possible Mai bhi padhta hun Fir dekhte hain if we can conclude something

The problem with this though is that epoxidation ka product isn't anyway nearly as stable as baeyer villiger ka product And the fact that it depends on the situation (Backed by data) Proves it furthermore

CorrodedCoffinOP•3mo ago
ughh so confusing final verdict??

Haven’t made one until now Trust me, you won’t see this in jee I’ll still answer you ‘cause I wanna know too
