क्या होता है, जब-
(i) ऐसीटैल्डिहाइड फेहलिंग विलयन से क्रिया करता है;
(ii) ऐसीटिक अम्ल फॉस्फोरस पेंटाक्लोराइड से क्रिया करता है
What happens, when-
(i) acetaldehyde reacts with Fehling solution;
(ii) acetic acid reacts with phosphorus pentachlo​

Answer 1

(i) acetaldehyde reacts with Fehling solution:

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

(ii) acetic acid reacts with phosphorus pentachlo​ide

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.
