Answer 1

2СН3-СН2-СН2-СООН + Mg --> (СН3-СН2-СН2-СОО) 2Mg + Н22СН3-СН2-СН2-СООН + MgO --> (СН3-СН2-СН2-СОО) 2Mg + Н2OСН3-СН2-СН2-СООН + KOH --> СН3-СН2-СН2-СООK + Н2O2СН3-СН2-СН2-СООН + CH3OH --> СН3-СН2-СН2-СОО-CH3 + Н2O

Answer 2

Chemical Properties of Butanoic Acid (C4H8O2)

Butanoic acid, also known as butyric acid, is a carboxylic acid with the chemical formula C4H8O2. It is a colorless liquid with a strong, unpleasant odor. Here are some of its key chemical properties:

1. Odor: - Butanoic acid has a strong, unpleasant odor, often described as rancid or like that of vomit.

2. Solubility: - It is soluble in water and organic solvents.

3. Reactivity: - Butanoic acid can undergo various chemical reactions, including esterification, oxidation, and decarboxylation.

4. Esterification Reaction: - Butanoic acid can undergo esterification to form esters. The general equation for the esterification reaction is: ``` RCOOH + R'OH → RCOOR' + H2O ``` Where R and R' represent alkyl or other organic groups.

5. Oxidation Reaction: - Butanoic acid can be oxidized to form carbon dioxide and water. The general equation for the oxidation reaction is: ``` 2C4H8O2 + 7O2 → 8CO2 + 8H2O ```

6. Decarboxylation Reaction: - Butanoic acid can undergo decarboxylation to form butane and carbon dioxide. The general equation for the decarboxylation reaction is: ``` RCOOH → R-H + CO2 ``` Where R represents an alkyl or other organic group.

These chemical properties make butanoic acid a versatile compound with various industrial and biological applications.
