on basis of solubility in water. ethyl acetate.
Yes
Plants material contains Organic compounds along with salts and water, some organic compounds are polar and soluble in ethyl alcohol or ethyl acetate but some are non polar and soluble in ether or hexane, so two types of solvents may be used for plants extraction, the best way is to use non polar solvent first and extract the non polar compounds then use the polar solvent and extract the polar compounds.
No.. Ethyl acetate is C2H5COOCH3 and Diethyl ether is C2H5OC2H5
DME (DiMethyl Ether) is rather unpolar because it is symmetrical (+-+), it has a bended or hooked (V-like) structure (about 120o corner) with 'longer, more spread legs' than water (104.5o). It is more polar than di-Ethyl ether however.
Old names are: Methyl Phenyl Ether and Propyl Ethyl etherOfficial names are: Methoxybenzene and ethoxy-1-propane
dipole-dipole attraction with Ethyl acetate molecules would overcome the H-bond attraction between Benzoic Acid molecules due to ratio of the non-polar to polar portion of the benzoic acid molecules to its polar
Petroleum and ether are NOT polar. Salt is polar.
It is polar
Ethylacetate is more polar. IT has a carbonyl group, which means the more electronegative Oxygen is drawing electron density towards oxygen, hence leaves the carbonyl carbon to be delta positive, hence there is polarity between those atoms of the molecule, then there is the ethyl group attached to this same carbonyl carbon, which although there is a degree of induction due to the CH2CH3 somewhat pushing towards the the carbonyl carbon, yet again the oxygen attached draws more density away, than the ethyl aspect pushing in, hence on both fronts, the molecule is polar. NOW in comparison to petroleum ether, well, petroleum ether, is usually short chained alkanes, either pentane, hexane, and is a fraction of refined oil. THE UPPER LIGHTER FRACTION, and not to be compared to say an actual ether, such as diethyl ether. So on that basis, pet ether is non polar. NOW if you meant diethyl ether. ETHYL ACETATE is still more polar, as the ether has one oxygen between methylene groups, or perhaps two methyl groups. and yes, there is an electronegative difference between that oxygen and the carbon next to it, but an ether is flanked by two carbon groups, hence the polarity of the molecule is minimized.
Petroleum and ether are NOT polar. Salt is polar.
Yes.
