    Acidity: carboxylic acid H2CO3 HCO3-(H+ can be provided) phenolic hydroxyl alcohol hydroxyl, according to the principle of forced weakness, the former can be prepared, the latter can not be obtained by reaction, so no, 3 can.

    Specifically, 1: If you can, NaHCO3 + phenolic hydroxyl sodium phenol hydroxyl + H2CO3 obviously does not comply with the above principles.

    As for learning, it is estimated that the landlord wants to learn well, but the foundation is not solid enough, and the current situation is not optimistic, right?! Then take practical action, listen to every class, do every question carefully, and strive to seek the help of teachers or classmates to solve every problem encountered, as long as you are a normal person, with perseverance and perseverance!! I believe that the olive branch of success will come at the right time.

    The carboxyl group is generally a carboxylic acid with less than 8 carbons, which can react with sodium carbonate to obtain sodium bicarbonate, or with sodium bicarbonate to obtain carbon dioxide, if the carbon chain is too long, the acidity is also very low, and it is difficult to react.

    The alcohol hydroxyl group is definitely not good, the ionization is too low, only the active metal such as sodium can seize the hydrogen inside, and the hydrogen in sodium bicarbonate is definitely not good.

    And what about phenol, it's not okay, why is that, because carbon dioxide is more acidic than phenol, and phenol is greater than sodium bicarbonate.

    In other words, if you put carbon dioxide into sodium phenol, you will get phenol and sodium bicarbonate (this sodium bicarbonate is not obtained by excessive carbon dioxide and sodium carbonate).

    Learning chemistry is the same as learning English, memorize everything you can remember, and then draw inferences from each other and improve according to the amount of exercises you have, don't rush!!

    NaHCO3 can react with carboxyl energy, but can not react with alcohol hydroxyl group, phenolic hydroxyl group, because the two of them are not acidic enough, this reaction finally generates carbonic acid, that is, carbon dioxide, to meet the law of strong acid to weak acid, only carboxylic acid acidity is greater than carbonic acid, the other two are small.

    1. Carboxyl group, i.e. -cooh, neutralized;

    2. The phenolic hydroxyl group, that is, the -OH directly connected to the benzene ring, is weakly acidic, but the alcohol hydroxyl group is neutral and does not react;

    3. Halogenated hydrocarbons, -x, hydrolyzed to produce alcohol, but note that the halogen atoms on the benzene ring do not react at room temperature.

    4. Ester group, -coo-, participates in hydrolysis reaction.

    5. Peptide bond, -conh-, hydrolysis.

    Phenol can be combined with sodium, sodium hydroxide.

    Sodium carbonate reacts with sodium bicarbonate.

    Reaction: 2C6H5OH+2Na 2C6H5ONa+H2, C6H5OH+NaOH C6H5OH+H2O, C6H5OH+Na2CO3 C6H5ONA+NaHCO3.

    Ethanol. Can only react with sodium: 2ch3ch2oh + 2na 2ch3ch2ona + h2

    Acetic acid can react with all four of these substances: 2CH3COOH+2NA2CH3COONA+H2, CH3COOH+NAOH CH3COONA+H2O, 2CH3COOH+NA2CO3 2CH3COONA+H2O+CO2, CH3COOH+NAHCO3 CH3COONA+H2O+CO2

    The carboxyl group reacts with all the latter to form sodium salt and water with sodium hydroxide, and sodium salt carbon dioxide and water with the latter two. Hydrogen gas is released by reacting with sodium.

    The alcohol hydroxyl group only reacts with sodium to release hydrogen. The rest do not respond.

    The phenolic hydroxyl group and sodium release hydrogen gas to form sodium phenol, with sodium hydroxide to form sodium phenol and water, with sodium carbonate to form bicarbonate and sodium phenol, and do not react with bicarbonate.

    The lipid group is hydrolyzed with sodium carbonate and sodium hydroxide to produce sodium salts and alcohols, with the former also releasing carbon dioxide. Reacting with sodium, sodium first reacts with water to form sodium hydroxide, which reacts with it.

    The aldehyde group is complex, and there will be a reduction reaction with sodium, which is partially reduced to alcohol, and sodium hydroxide will form alcohol and sodium carboxylate.

    The third inorganic in the question is na2co3, which is what I wrote:

    Phenolic hydroxyl group: 2ph-OH + 2Na = 2 ph-ONA + H2 PH-OH + NaOH = PH-OH + H2OPH-OH + Na2CO3 = PH-ONA + NaHCO3 does not react with sodium bicarbonate.

    Alcohol hydroxyl group: 2ET-OH+2Na=2ET-ONA+H2 and others do not react.

    Carboxyl: 2Ac-OH+2Na=2Ac-ON+H2 AC-OH+NaOH=AC-OA+H2OAC-OH+NA2CO3=AC-OA+NAHCO32AC-OH+NA2CO3=2AC-OH+H2O+CO2 AC-OH+NAHCO3=AC-OA+H2O+CO2 Hope it helps you.

    <> phenolic hydroxyl group and alcohol hydroxyl group are not a functional group of Huai Mo. Functional groups are atoms or groups of atoms that determine the chemical properties of organic compounds. Common functional groups include hydroxyl groups, carboxyl groups, ether bonds, aldehyde groups, carbonyl groups, etc.

    Organic chemical reactions mainly occur on functional groups, which play a decisive role in the properties of organic matter. —X, lead forebucket-OH, -cho, -cooh, -NO2, -SO3H, -NH2, RCO-, these functional groups determine the chemical properties of halogenated hydrocarbons, alcohols or phenols, aldehydes, carboxylic acids, nitro compounds or nitrites in organic matter.

    Alcohol hydroxyl group: Na only

    Phenol hydroxyl group (phenol): Na, Naoh, Na2CO3 because the acidity of the alcohol hydroxyl group is very weak (pka=17, acidity is less than water), so it cannot be reflected by metathesis reaction with the alkali that can exist in water (the alkalinity of the alkali is not enough), and can only be reflected by the displacement reaction with the active metal.

    However, the phenolic hydroxyl group increases the polarity of the O-H bond due to the electron-absorbing effect of the benzene ring. At the same time, in the anion formed after ionization of H+, the benzene ring can also effectively disperse the negative charge. Therefore, the acidity of the phenolic hydroxyl group is relatively strong (stronger than that of water, and the acidity of different phenols is quite different), and its acidity can be reflected by metathesis reaction with a part of the alkali that can exist in water.

    In the case of phenol, because its acidity is less than H2CO3, it cannot react with NaHCO3 to release CO2.

    Reacting with the alcohol hydroxyl group is sodium.

    Reacting with the phenolic hydroxyl group is sodium hydroxide.

    This is not an alcoholization reaction, acid dehydroxyl group, alcohol dehydrogenation reaction, this is an esterification reaction.

    Malic acid is the common name of hydroxysuccinic acid, it does have a hydroxyl group and a carboxyl group in the molecule, at this time the two functional groups can react, because the hydroxyl group in the carboxyson and the hydrogen in the hydroxyl group are present, so its two functional groups can react, it can occur under the action of concentrated sulfuric acid, the intermolecular esterification reaction can occur, and the intramolecular esterification reaction can also occur to form lactone.

    1) Ox Acid --2-Hydroxysuccinic Acid Hooc-CH(OH)CH2-COOH

    2) The carboxyl group is esterified with the alcohol hydroxyl group!

    3) Malic acid can be interesterified with molecules; Lactones can also be formed by molecular lactification.

    First of all, let's talk about three basics, 1 phenolic hydroxyl group is weakly acidic, although it is weak, but it is also an acid. 2. Sodium is an alkali metal, the metal is extremely active, and can react with acids in a broad sense, the so-called acid in a broad sense, that is, it can ionize hydrogen ions, including water and some strong acids and weak alkali salts. 3 ethanol reaction with sodium metal is an example, not all metals are OK, because the energy required for the whole hydroxyl group to break is much lower than that of a single drop of hydrogen, for example, a wooden stick with uneven thickness, the easiest to break is the thinnest piece, and between the entire hydroxyl group and the previous ethyl group, it is the thinnest piece.

    First of all, it must be sodium metal, which can be reacted, but the mechanism of the reaction is different. Second, sodium ions should be an idiom and phenol ion exchange, strictly speaking, it is not a reaction, and alcohol, simply will not change. Third, since ethanol and sodium ions are unreactive, there is no such thing as a reaction order.
