Question

Составить структурную формулу жиров : этиловый спирт ⟶ ацетальдегид ⟶ уксусная кислота ⟶ метиловый эфир уксусной кислоты ⟶ ацетат калия.

Answer 1

Ответ:

2C 2 H 5 OH + O 2 t, кат. ⟶ 2CH 3 CHO + 2H 2 O 2CH 3 CHO + O 2 t, кат. ⟶ 2CH 3 COOH CH 3 COOH + CH 3 OH `overset(H⁺)(⇄)` CH 3 COOCH 3 + H 2 O⇄H⁺⇄H⁺CH CH 3 COOCH 3 + KOH ⟶ CH 3 COOK + CH 3 OH

Answer 2

Structural Formula of Fats:

The structural formula of fats can vary depending on the specific type of fat. However, in general, fats are composed of glycerol and fatty acids. Glycerol is a three-carbon alcohol with three hydroxyl groups (-OH), while fatty acids are long hydrocarbon chains with a carboxyl group (-COOH) at one end.

The structural formula of a fat can be represented as follows:

Glycerol: C3H8O3

Fatty Acid: R-COOH, where R represents the hydrocarbon chain

When glycerol reacts with three fatty acids, a triglyceride molecule is formed. The reaction involves the removal of three water molecules, a process known as esterification. The structural formula of a triglyceride can be represented as:

Triglyceride: R-CO-O-CH2-CH(OH)-CH2-O-CO-R

Where R represents the hydrocarbon chains of the three fatty acids.

Ethyl Alcohol to Acetaldehyde:

The conversion of ethyl alcohol to acetaldehyde involves the oxidation of the alcohol group (-OH) to an aldehyde group (-CHO). The structural formula of ethyl alcohol is C2H5OH, and the structural formula of acetaldehyde is CH3CHO.

Acetaldehyde to Acetic Acid:

The conversion of acetaldehyde to acetic acid involves the oxidation of the aldehyde group (-CHO) to a carboxyl group (-COOH). The structural formula of acetic acid is CH3COOH.

Acetic Acid to Methyl Acetate:

The conversion of acetic acid to methyl acetate involves the esterification of acetic acid with methanol. The structural formula of methyl acetate is CH3COOCH3.

Methyl Acetate to Potassium Acetate:

The conversion of methyl acetate to potassium acetate involves the reaction of methyl acetate with potassium hydroxide. The structural formula of potassium acetate is CH3COOK.
