Which is more polar acetonitrile or methnol?
polar solvents dissolved in water most of times ,and methnol,acetonitrile
Acetonitrile is slightly more polar than methanol. This is due to the presence of the C-N triple bond in acetonitrile (CH3CN).
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.
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.
Yes, chloroform is soluble in acetonitrile. Acetonitrile is a polar solvent, while chloroform is a nonpolar solvent, but they can still mix together and form a homogeneous solution.
Castor oil is a triglyceride derived from castor beans and is primarily composed of ricinoleic acid. It is generally non-polar, which makes it less soluble in polar solvents like acetonitrile. However, some solubility may occur due to the presence of polar functional groups in castor oil, but it is expected to be low. Overall, the solubility of castor oil in acetonitrile is limited.
The reaction between water and acetonitrile typically does not occur spontaneously due to the difference in polarity between the two compounds. Acetonitrile is a polar aprotic solvent while water is a polar solvent. In some cases, a reaction may occur under specific conditions with the presence of a catalyst or under harsh conditions.
Yes, acetonitrile is an organic compound. It is a colorless liquid with a chemical formula CH3CN, consisting of carbon, hydrogen, and nitrogen atoms. It is commonly used as a polar aprotic solvent in various chemical reactions.
Approximately 0.36 of the total amount in the container.
Approximately 6.6 pounds of acetonitrile can be found in 1 gallon.
To make 1% acetic acid in acetonitrile, you would mix 1 part acetic acid with 99 parts acetonitrile by volume. For example, if you want to make 100mL of 1% acetic acid in acetonitrile, you would mix 1mL of acetic acid with 99mL of acetonitrile. Remember to handle acetic acid carefully as it can cause skin and eye irritation.
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.
