Answered by RitaNarine

The compound A would be ethyl alcohol which is colourless liquid having a burning taste.when the vapour of a compound is passed over heated copper at 573 K , it is dehydrogenated to acetaldehyde.

• Here the copper helps to complete the dehydrogenation and here the copper helps to lose the hydrogen of ethyl alcohol and give an aldehyde (acetaldehyde).

• The balanced equation would be

CH3CH2OH —CH3CHO+H2 (in the presence of over heated copper at 573k)
