2. perform esterifigation reaction with ethanol.

Answer 2

Acetic acid is an organic acid which is the principal element of vinegar. It is also called glacial acetic acid, ethanoic acid or methane carboxylic acid.

CH3OH + CO + Rh/I2 → CH3COOH

Physical properties: Pure acetic acid is a colorless liquid with an intense, caustic pungent odor. Its density is 1.05 g/mL, and the boiling point is 118 °C. It has a distinctive sour taste and is highly miscible in water.

Chemical properties: Acetic acid is a weak acid. As a carboxylic acid, it forms standard derivatives such as acid chlorides, anhydrides, esters and amides. It can be subdued (removal of oxygen or addition of hydrogen) to produce ethanol. When heated above 440 °C, it decomposes to give carbon dioxide and methane:

CH3COOH → CH4 + CO2
