Acetonitrile is a more polar molecule than methanol because of the triple bond and lone pair on the nitrogen (N) atom in acetonitrile. This makes that end of the molecule highly electronegative, even more so than an oxygen (O) atom containing two lone pairs in methanol.

Is methanol more polar than acetone?
Methanol is more polar because is capable of dipole-dipole interactions AND hydrogen bonding while acetone is capable of just dipole-dipole interaction.
Methyl alcohol ionic polar or non polar?
methanol is polar molecule.
Which is more polar Trifluoroacetic acid or Acetonitrile?
In aqueous buffers, trifluoroacetic acid will be more polar because it will ionize to form trifluoroacetate. Acetonitrile has no acid/base chemistry and will not ionize. Since ions are very, very "polar", trifluoroacetate wins. I guess the answer may depend on the solvent, though. Both acetonitrile and TFA are highly polar, even when not ionized. Witness their complete miscibility with water, e.g. polarity depends on polarising groups/atoms. In trifluroacetic acid polarity is due to electronegativity and resonance which stabilises the anion. in the case of acetonitrile polarity is due to the electronegative difference between carbon and nitrogen.
Is ch3oh non polar covalent or polar covalent?
Methanol is a polar covalent compound.
Why was methanol an appropriate solvent to precipitate polystyrene?
Methanol is used to force polystyrene OUT of solution. So the simple answer is: you can't. But, there is probably an extreme temperature or pressure that allows polystyrene to remain in solution with methanol present.
What compound is more polar and soluble in water methane or methanol and why?
Acetonitrile is slightly more polar than methanol. This is due to the presence of the C-N triple bond in acetonitrile (CH3CN).

Why is acetonitrile more polar Why not methanol.O is more electro-ve. my guess is that nitrogen is in the end in the molecule whereas in methanol oxygen has hydrogen on one hand and carbon on another?
In Acetonitrile carbon (EN-value on Pauling's scale is 2.5) of cyanide is attached with Nitrogen(EN-value on Pauling's scale is 3.0), so , Nitrogen atom with combination of carbon, that is more EN than Hydrogen(EN-value on Pauling's scale is 2.1) attached with oxygen atom (EN-value on Pauling's scale is 3.5) in methanol, becomes more Electron withdrawing effect than -OH group in methanol. In this way -CN is more dispersive than that of -OH.
Solubility of azithromycin?
rapidly soluble in methanol , Acetonitrile and partially soluble water .
How do you dissloved polar solvents?
polar solvents dissolved in water most of times ,and methnol,acetonitrile

What are polar and non-polar liquids?
A polar liquid is a liquid that does not have any/much of a hydrocarbon chain and has mainly OH, NH or even C=O or C=-N groups. As you increase the carbon chain, you become less polar. Polar solvents include water, dimethylformamide, ethanol, methanol, acetonitrile to name a few. Non polar solvents include pentane, hexane, toluene, heptane to name a few.
Is methanol more soluable than methane?
Yes, methanol is CH3OH and methane is CH4. Methanol is polar (because of the O-H bond) and methane is non-polar (because it is a hydrocarbon.) Water (which is polar) will dissolve other polar things, but not non-polar things.
What would happen to the isolation process if you use a more polar solvent such as methatnol inteasd of dietyl ether?
Most of the organic compounds are not sufficiently polar and are insoluble in polar solvent like methanol so only polar fractions may be separated by using methanol.
Why is methanol more polar than ethanol?
Methane is CH4 or H-CH3 Ethane is CH3-CH3 When compared to H- (in methane), the CH3- (methyl group in ethane) is more electron donating and hence ethane is more basic than methane.
