Vedclass · Answer

(A) When alcohols are passed over heated copper at $300\,^\circ C$,dehydrogenation occurs for primary and secondary alcohols,while dehydration occurs for tertiary alcohols.$1$. Primary alcohols $(R-CH_2OH)$ are oxidized to aldehydes $(R-CHO)$.$2$. Secondary alcohols $(R_2CHOH)$ are oxidized to ketones $(R_2CO)$.$3$. Tertiary alcohols $(R_3COH)$ undergo dehydration to form alkenes (olefins) $(R_2C=CH_2)$.$4$. Phenol does not undergo this reaction to form benzyl alcohol; in fact,benzyl alcohol is a primary alcohol that would form benzaldehyde under these conditions. Therefore,the conversion of phenol to benzyl alcohol is chemically incorrect.

Which of the following reactions will $NOT$ occur with heated copper at $300\,^\circ C$?
