Answer 1

Answer:

1.

When acetaldehyde is heated with Fehling's solution, a red precipitate is formed.

CH3CHO + 2Cu^+ + 5OH−→CH3CO^− + Cu2O + 3H2O

2.

When acetic acid is heated with phosphorus pentachloride, acetyl chloride is obtained. In this reaction, −COOH group is converted to −COCl group. The side products are phosphorus oxychloride and HCl.
