Vedclass · Answer

(A) When alcohols are passed over heated copper at $300 \ ^oC$,they undergo dehydrogenation or dehydration.$1^\circ$ alcohols are dehydrogenated to aldehydes.$2^\circ$ alcohols are dehydrogenated to ketones.$3^\circ$ alcohols undergo dehydration to form alkenes (olefins).Phenol does not undergo this reaction to form benzyl alcohol,as the structure of phenol $(C_6H_5OH)$ cannot be converted to benzyl alcohol $(C_6H_5CH_2OH)$ through this process.

Which of the following is not true in case of reaction with heated copper at $300 \ ^oC$?
