Stability of enoliccontent: Important factors:Solvent: In polar solvent e.g water,alchohol,acetic acid etc,which can form Hbonding with C=O group,enolic content decreases while in non polar solvent e.g Hexane,benzene etc. enolic content increases..e.g: enolic content of aceto acetic ester is Methanol =7% in Hexane=46%.

This can be best explained with resonance. It gives the molecule more stability since it can distribute it's electrons around and hence, it's charge, making it less likely for it to accept a proton

what has that got to do with hydrogen bonding?
 one year ago

abb0t Group TitleBest ResponseYou've already chosen the best response.0
I think what it's saying is that due to the ability of the electrons to do more resonance, distributing it's charge, it increases it's enolic properties. I don't rly understand the last part though. acetoacetic ester methanol = 7%?

aceto acetic ester in* Methanol =7% in Hexane=46%.

i think its not IS in "content of aceto acetic ester is Methanol =7% in Hexane=46%" its in. in methanol, in hexane. In hexane hidrogen bonds are less likely to happen, or don't happen at all, cous its nonpolar. As methanol is a polar solvent, hidrogen bonds can be formed. interfering with the C=O bond.

resonance decreases if the oxygen from ceto has a polar molecule interfering, i guess

Can you tell me which is more polar ? enol form or keto form ?

Reason ?

no idea,wild guess

because delta minus is higher on the ceto. oxygen has higher delta

Intra molecular hydrogen bonding.

shubhamsrg Group TitleBest ResponseYou've already chosen the best response.0
Intra molecular hydrogen bonding is the reason that enol form is less polar than keto form.

what effect is Hbonding producing?(4th time)
 one year ago

shubhamsrg Group TitleBest ResponseYou've already chosen the best response.0
Thus, more polar the solvent, more polar form will be preferred. i.e. keto form is preferred for more polar solvents.

i actually forgot that :/ and i dont know its application like when does it occur n stuff

btw, iam not quite sure if ceto is more polar then enolic form..

andrefontex Group TitleBest ResponseYou've already chosen the best response.0
they existe both forms, but depending on circumstances, it will occur the more stable one
