Vedclass · Answer

(A) When primary alcohols $(R-CH_2OH)$ are passed over red-hot copper at $573 \ K$,they undergo dehydrogenation to form aldehydes $(R-CHO)$.When secondary alcohols $(R_2CHOH)$ are passed over red-hot copper at $573 \ K$,they undergo dehydrogenation to form ketones $(R_2C=O)$.Therefore,primary and secondary alcohols yield aldehydes and ketones respectively.

What is obtained by the reaction of primary and secondary alcohols with red-hot copper at $573 \ K$?
