Question

what happens when Ethanol is treated with Copper(cu) at 300°C?​

Answer 1

Answer:

,When the vapours of an alcohol are passed over copper catalyst heated at 573K. it undergoes dehydrogenation (loss of hydrogen or oxidation). The product formed depends on the alcohol and hence this reaction is also used to distinguish the three classes of alcohols.

Answer 2

Copper at 300°C is the reagent for dehydrogenation. When vapours of primary or secondary alcohol is are passed over Cu at 300°C, result in the formation of aldehyde (with primary alcohol) and ketone (with secondary alcohol).

Tertiary alcohols are oxidized to alkenes ( called dehydration )  with Cu at 300°C.

Ethanol is a primary two carbon alcohol. It will be converted to two carbon aldehyde or Ethanal ( Acetaldehyde )

$CH_3-CH_2-OH \frac{Cu( 300^oC)}{}> CH_3-CHO$
