Question

Write the chemical reaction when hot copper is treated with Vapours of 1° (primary) alcohol.

Answer 1

Hot copper with 1 ° (primary) alcohol gives aldehyde.

\[\ce{\underset{( 1° alcohol)}{R-CH2OH}->[Cu][573 K]\underset{(Aldehyde)}{R-CHO}}\]

e.g \[\ce{\underset{(Ethanol)}{CH - CH2OH}->[Cu][573 K]\underset{(Ethanal)}{CH - CHO}}\]
