Compare the size of acetic acid, phenol, ethanol, water, acidity, and why

Comparing the strength of acidity is actually comparing the ability of each solution to ionize hydrogen ions. It can be compared with some common phenomena.

Acetic acid can discolor acid-base indicators while others cannot, so acetic acid is the most acidic.

The second is phenol, which can react with general bases (such as NaOH), while ethanol and water cannot.

Again, there is water, although it is usually considered to be neutral, but it is still relatively "acidic" compared to ethanol. It can be seen by the violent reaction between na, water, and ethanol. (The essence of the reaction between NA and water and ethanol is that NA replaces the H element in it) The reaction between NA and water will be very violent, which is in our high school textbooks, and the reaction with ethanol is also there, so it can be seen that the reaction between NA and water is more intense, and the reaction with ethanol is not too violent, and it can also be said that it is carried out slowly at all.

To sum up, the acidity is acetic acid phenol water ethanol.

Acidic order: acetic acid, phenol, water, ethanol.

Reason: The size of the acidity depends on the polarity of the oxygen-hydrogen bond in the molecule, the greater the polarity, the easier it is to be dissociated, and thus the more acidic. The polarity is determined by the group attached to -OH, and the stronger the power absorption capacity of the group, the stronger the polarity of the -OH bond.

The order of electron-withdrawing capacity is CH3-CO->C6H5->H->CH3CH2-.

Acidic order: acetic acid, phenol, water, ethanol.

Because of the alkaline CH3-CoO-

Acidity: acetic acid, carbonic acid, phenol, ethanol.

1) Ethanol is a neutral substance.

2) Acetic acid is acidic:

ch₃cooh⇋ch₃coo⁻+h⁺

2ch₃coona+na₂co₃=2ch₃coona+h₂o+co₂↑

3) Phenol is extremely weakly acidic

C H -oh + h o c h -o +h o c h ona+co +h o=c h oh + nahco (4) Carbonic acid is weakly acidic: H co H + HCO, which is stronger than phenol and weaker than acetic acid.

The reaction of phenol and sodium carbonate can only give sodium phenol and sodium bicarbonate, which proves that phenol is less acidic than carbonic acid.

Acetic acid and sodium carbonate are reacted to give sodium acetate and carbonic acid (carbon dioxide and water), proving that acetic acid is more acidic than carbonic acid.

Ethanol does not react with sodium phenol, proving that ethanol is less acidic than phenol (in fact, it is not acidic at all), so the result is 2>4>3>1

In fact, it is to use strong acid to put weak acid.

2>4>3>1

PKA: ethanol:, acetic acid:, phenol:, carbonic acid:

Phenol (chemical formula: C6H5OH) and ethanol (chemical nuclear formula: C2H5OH) are both compounds that contain hydroxyl (OH) functional groups, but they differ in their acidic properties.

Phenol is a weak acid that releases hydroxyl ions (OH-). In water, phenol is partially ionized into phenol anions (C6H5O-) and hydrogen ions (H+), which helps to increase the acidity of the solution. But due to the relatively weak acidic nature of phenol, it is less ionized in pure water.

Ethanol can also be considered a weak acid, but it is less acidic than phenol. When ethanol reacts with water, it produces a small amount of hydrogen ions, releasing a small amount of H+ ions. However, the degree of ionization of ethanol in pure water is extremely limited.

Phenol is slightly more acidic than ethanol. However, they are both weaker in acidity compared to some strong acids, such as hydrochloric acid or modified sulphuric acid. It is important to note that their acidic nature may change under certain conditions, such as in reactions. <>

Water, ethanol, phenol, C2H2 which is the most acidic.

Hello, I found out for you: water and ethanol are alcohols, which are weakly acidic substances, while C2H2 (acetylene) is an alkane-cultured freekyne, not an acidic substance. As a result, phenol is the most acidic.

The hydroxyl group in the phenol molecule forms a covalent bond with the benzene ring, which is an enol-like structure, due to the stability of the benzene ring, the reaction is more active, and it is easy to lose hydrogen ions to become the negative ions of phenol, so phenol has strong acidity in pure history.

Summary. Ethyl acetate has a lower boiling point than acetic acid because of the presence of a hydrogen bond in the ethyl acetate molecule, which increases the interaction between molecules, thereby reducing the boiling point. Workaround:

1.Increase the number of hydrogen bonds in the molecule: By changing the molecular structure and increasing the number of hydrogen bonds in the molecule, the interaction force between the molecules can be enhanced, thereby reducing the boiling point.

2.Increase the size of the molecule: By changing the molecular structure and increasing the size of the molecule, the interaction force between the molecules can be increased, thereby reducing the boiling point.

3.Increase molecular weight: By changing the molecular structure and increasing the molecular weight, the interaction force between molecules can be increased, thereby reducing the boiling point.

4.Increase the polarity of the molecule: By changing the molecular structure and increasing the polarity of the molecule, the interaction force between the molecules can be increased, thereby reducing the boiling point.

The above are the reasons and solutions for the lower boiling point of ethyl acetate than acetic acid.

Ethyl acetate has a lower boiling point than acetic acid because of the presence of a hydrogen bond in the ethyl acetate molecule, which increases the interaction between molecules and lowers the boiling point from the bond. Workaround:1

Increase the number of hydrogen bonds in the molecule: By changing the molecular structure and increasing the number of hydrogen bonds in the molecule, the interaction force between the molecules can be enhanced, thereby reducing the boiling point. 2.

Increase the size of the molecule: By changing the molecular structure and increasing the size of the molecule, the interaction force between the molecules can be increased, thereby reducing the boiling point. 3.

Increase molecular weight: By redrafting the silver molecular structure and increasing the molecular weight, the interaction force between molecules can be increased, thereby reducing the boiling point. 4.

Increase the polarity of the molecule: By changing the molecular structure and increasing the polarity of the molecule, the interaction force between the molecules can be increased, thereby reducing the boiling point. The above is the reason and solution for the lower boiling point of ethyl acetate than that of acetic acid.

You've done a great job! Can you elaborate on that?

The boiling point of ethyl acetate is lower than that of acetic acid, mainly due to the existence of hydrogen bonds between acetic acid and ethyl ester in the ethyl acetate molecule, which makes the interaction force between ethyl acetate molecules weaker than that between acetic acid molecules, thus making the boiling point of ethyl acetate lower than that of acetic acid. In addition, the molecular weight of the ethyl acetate molecule is larger than that of the acetic acid molecule, and the surface area of the ethyl acetate molecule is also larger than that of the acetic acid molecule, which is one of the reasons why the boiling point of ethyl acetate is lower than that of acetic acid. Ethyl acetate has a lower boiling point than acetic acid, which is one of the reasons why ethyl acetate is more volatile than acetic acid.

Ethyl acetate is more volatile than acetic acid, so ethyl acetate is more volatile, whereas acetic acid is less volatile. Ethyl acetate has a lower boiling point than acetic acid, which is one of the reasons why ethyl acetate is more soluble in organic solvents than acetic acid. Ethyl acetate has greater solubility than acetic acid, so ethyl acetate is more soluble in buried machine solvents, while acetic acid is less soluble in organic solvents.

Comparison of acidity of alcohol, water, phenol, carbonic acid, carboxylic acid.

Alcohols, hydrophenols, carbonic acids, and carboxylic acids are all acids in chemistry. From the point of view of acidity, carboxylic acids are the most acidic, followed by hydrophenols and carbonic acid, and alcohols are the weakest. This is because the carboxylic acid molecule contains a carboxyl group (-Cooh), which is able to release hydrogen ions (H+) in a multi-chamber cavity, which is more acidic.

The round nucleus in hydrophenol and carbonic acid molecules also contains sites for the release of hydrogen ions, but is less acidic than carboxylic acids. There is no site for the release of hydrogen ions in the alcohol molecule, so alcohols are the least acidic.
