What else can I help you with?
What is meant by 99 percent assay of ethyl acetate?
That is the concentration of the compound within a solvent. It's basically the purity of your sample of the compound (in this case ethyl acetate). So it could be equal to or greater than 99% ethyl acetate and the rest would be ethanol or some chemical that the ethyl acetate is dissolved in.
Is chloroform more polar than ethyl acetate?
Yes, chloroform is more polar than ethyl acetate. Chloroform has a higher dipole moment due to the greater difference in electronegativity between the carbon and chlorine atoms, making it more polar than ethyl acetate.
How would you expect Rf values to change if you went from hexane-ethyl acetate solvent system to ethyl acetate only?
If you switch from a hexane-ethyl acetate solvent system to ethyl acetate only, you would expect the Rf values to decrease. Ethyl acetate is a more polar solvent than hexane, so compounds will interact more with the solvent and have shorter distances of travel on the TLC plate, resulting in lower Rf values.
On the basis of its boiling point identify the pure liquid as either ethyl acetate or butyl acetate?
To identify a substance, you must find more than its boiling point. Also look for its freezing point and density.
Solubility of ethyl cellulose?
Practically insoluble in water, in glycerol, and in propane-1,2-diol, but soluble in varying proportions in certain organic solvents, depending upon the ethoxyl content. Ethyl cellulose containing less than 46-48% of ethoxyl groups is freely soluble in tetrahydrofuran, in methyl acetate, in chloroform, and in aromatic hydrocarbon ethanol mixtures. Ethylcellulose containing 46- 48% or more of ethoxyl groups is freely soluble in ethanol, in methanol, in toluene, in chloroform, and in ethyl acetate.
What is denser ethyl acetate or water?
water is more dense than ethyl acetate , so water remains on bottom and ethyl acetate on top when both mixed.
Is ethyl acetate more polar than toluene?
Yes, ethyl acetate is more polar than toluene.
Is silica more polar than ethyl acetate?
Yes silica is more polar then ethyl acetate . Deepak
What is more polar either ethyl-acetate or pet-ether?
on basis of solubility in water. ethyl acetate.

Are methyl cation is more stable than ethyl cation?
An ethyl cation is more stable because the carbon adjacent to the positively charged carbon has three sigma bond orbitals available for overlap with the vacant p orbital, whereas methyl cation does not have any sigma bond orbitals available for overlap with the vacant p orbital.
Ethyl acetate and water forms an azeotrope?
True. Ethyl acetate and water do form an azeotrope at a specific composition, where the vapor phase has the same ratio of ethyl acetate to water as the liquid phase. This azeotrope has a boiling point lower than that of either pure component.
Why ethylacetate is more polar than chloroform?
Ethyl acetate is more polar than chloroform because it contains both an ester functional group and an oxygen atom, leading to a higher dipole moment and increased polarity. In contrast, chloroform only contains a single electronegative chlorine atom, making it less polar than ethyl acetate.
