Acetaldehyde is oxidized oversilica gel with the help of air. A mixture of acetaldehyde and do
air is passed over a silica gel catalyst at 386 K. The following reactions take place
CH CHO 02 CHCOOH

The outgoing a gas is found to contain: 58% EOL, 8-56967 acetaldehyde 1526 ctia
acid 255% and 69.05 by volume on dry basis. For the purpose of dry analysis
water was first removed from the mixture and some acetic acid was also removed along with

Answer 1

Answer:

pH = 1

pH = 3.5

Any value of pH

pH = 12.

Answer :

B

Solution :

Aldehydes/ketones reacts with ammonia derivative like (hydrazine, NH2NH2NH2NH2, hydroxyl amine, NH2OHNH2OH etc.) under slighty acidic conditions (pH = 4.5)
