Can ethanol undergo an addition reaction?!

No, because ethanol is already saturated alcohol, and all covalent bonds are already single bonds. Upstairs said that it should be eliminated first and then added.

No, you need an unsaturated bond for the addition reaction to occur.

It can be Celsius, ether is generated, 170 degrees Celsius, ethylene.

The chemical equation for the reaction of ethanol with concentrated sulfuric acid.

CH3CH2OH --(170 degrees Celsius, concentrated H2SO4)--CH2==CH2+H2O2CH3CH2OH--(140 degrees Celsius, concentrated H2SO4)--CH3CH2OCH2CH3 (ether) + H2O They are the addition reaction Characteristics of the addition reaction: After the addition reaction is carried out, the heavy bond is opened, and the atoms at both ends of the original heavy bond are connected to a new group. The addition reaction is generally the reaction of two molecules to form one molecule, which is equivalent to the chemical reaction of inorganic chemistry.

For example, CH2CH2, with the addition of BR2, ethylene breaks the double bond by one bond, and the covalent bond of BR2 is also broken, and the two BR atoms are connected to the C atom that breaks the double bond. The addition reaction can occur because double or triple bonds are more reactive as compared to single bonds. As for the mechanism, nucleophilic, electrophilic, stereochemical, trans-cis, you should not know yet.

Ethanol has no unsaturated bonds and does not undergo addition reactions.

Is this an addition reaction? Isn't it just intramolecular dehydration?

Ethylene and Songjing water can be added to produce ethanol, and Fang's journey formula is C H + H O - (under certain conditions) C h Oh

The two atoms at the end of the reactant molecule bound by heavy bonds or conjugated unsaturated systems are bonded to groups or atoms provided by the reagent respectively in the reaction to obtain a saturated or relatively saturated addition product. This addition can be a stable wild nucleus age; It can also be an unstable intermediate that undergoes further changes to form a stable product.

Acetic acid and ethanol undergo esterification reaction CH3COOH + CH3CH2OH = CH3COOC2H5 + H2O

Ethanol can undergo nucleophilic substitution reactions, but generally cannot be added.

Acetic acid can undergo esterification reactions, and its ortho-H can also be substituted, both of which seem to be substitution reactions. Acetic acid is generally not additional and can only be reduced with lialh4.

Acetaldehyde can be nucleophilic, catalyzed hydrogenation, or aldol condensation (aldol condensation can be seen as a substitution reaction).

Acetaldehyde can undergo substitution reactions, such as with hydrogen, which cannot be replaced... Acetic acid has no addition [can be special, as if it is reacted by BNH4], no substitution. Ethanol has no addition, no substitution. It can be replaced with sodium.

The esterification of ethanol acetic acid is substitution, so ethanol and acetic acid can be replaced.

Ethanol has no unsaturated bonds, so it cannot be added;

Acetic acid has an unsaturated bond, but the unsaturated C and H are connected to the same C with aerobic elements, so acetaldehyde can be added and cannot be replaced. I don't know how to chase.

Ethanol can be esterified (substituted) with carboxylic acids, acetic acid can be esterified (replaced) with alcohols and phenols (but it will be more difficult with phenols).

Acetaldehyde can undergo addition (also reduction) reaction with hydrogen to form acetic acid because of its carbon-oxygen double bond, and only the carbon-oxygen double bond in aldehyde will be added to form the corresponding acid without substitution.

Analysis Duan Zhengji Under light conditions, methane and toluene can undergo substitution reactions, methanol.

Esterification can occur, and esterification is also a substitution reaction. Polyethylene.

does not contain an unsaturated bond, so an addition reaction cannot occur, and option b is incorrect; Lipids and fats are glycerides of fatty acids in high-grade fatots, which are not polymer compounds. respectively to ethanol.

The colorless phenolphthalein test solution added to acetic acid is still colorless, so it cannot be identified by the colorless phenolphthalein test solution, and option d is wrong. A
