Question

What happens when ethanol is treated with cu at 573 k?

Answer 1

Answer:

When ethanol is heated with Cu at 573 K, it gets oxodized to ethanal. Phenol is treated with acetyl chloride in presence of anhydrous AlCl3 to form m-acylphenol and p-acylphenol. Ethyl chloride when treated with sodium methoxide gives ethyl methyl ether.

Answer 2

Oxidation reaction occurs when ethanol is heated at 573K with copper, resulting in the formation of ethanal.

• Ethanol belongs to the class of alcohols, with a molecular formula $C_{2} H_{5} OH$.
• Copper acts as an oxidizing agent in the reaction.
• Alcohols yield carbonyl compounds on oxidation. Primary alcohols form aldehydes whereas secondary and tertiary alcohols get converted to ketones.
• Ethanol is a primary alcohol and so forms an aldehyde, ethanal, or acetaldehyde.
• The reaction is as follows:

                             $CH_{3} CH_{2} OH + Cu$   →  $CH_{3} CHO$
