Vedclass · Answer

(D) The reaction of alcohols with $Cu$ at $573 \ K$ is a dehydrogenation reaction,not dehydration.$1$. Primary alcohols $(RCH_2OH)$ form aldehydes.$2$. Secondary alcohols $(R_2CHOH)$ form ketones.$3$. Tertiary alcohols $(R_3COH)$ undergo dehydration to form alkenes because they cannot undergo dehydrogenation due to the absence of $\alpha$-hydrogen.Since the question asks for the reaction with $Cu$ at $573 \ K$,tertiary alcohols specifically undergo dehydration under these conditions. Therefore,the correct option is $D$.

Which of the following alcohols undergo a dehydration reaction with $Cu$ (copper) metal at $573 \ K$ temperature?
