Best ResponseYou've already chosen the best response.0Stability 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%.

Best ResponseYou've already chosen the best response.0This 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

Best ResponseYou've already chosen the best response.0what has that got to do with hydrogen bonding?

Best ResponseYou've already chosen the best response.0I 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%?

Best ResponseYou've already chosen the best response.0i 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.

Best ResponseYou've already chosen the best response.0resonance decreases if the oxygen from ceto has a polar molecule interfering, i guess

Best ResponseYou've already chosen the best response.0Can you tell me which is more polar ? enol form or keto form ?

Best ResponseYou've already chosen the best response.0because delta minus is higher on the ceto. oxygen has higher delta

Best ResponseYou've already chosen the best response.0Intra molecular hydrogen bonding.

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

Best ResponseYou've already chosen the best response.0what effect is Hbonding producing?(4th time)

shubhamsrg

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

Best ResponseYou've already chosen the best response.0btw, iam not quite sure if ceto is more polar then enolic form..

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