Question

How does 1°,2°,3°alcohol react with cu at 573 k?​

Answer 1

Answer:

• Reaction of primary alcohols with Cu : Primary alcohols undergo dehydrogenation to form aldehydes.

$\boxed{\begin{minipage}{32 em} RCH_{2}OH \overset{Cu (573K)}{\longrightarrow}RCHO\\\\\textbf{Dehydrogenation of primary alcohols with Cu yields aldehydes/} \end{minipage}}$

• Reaction of secondary alcohols with Cu: Secondary alcohols undergo dehydrogenation to form ketones.

$\boxed{\begin{minipage}{32 em} RCH(OH)R_{1} \overset{\Cu(573K)}{\longrightarrow}R- (C=O)- R_{1}\\\\\textbf{Dehydrogenation of secondary alcohols with Cu yields ketones} \end{minipage}}$

• Reaction of tertiary alcohols with Cu: Tertiary alcohols undergo dehydrogenation to form alkenes.        

$\boxed{\begin{minipage}{32 em} R-[C(OH)-R_{2}]R_{1} \overset{Cu(573K)}{\longrightarrow} R- [C-R_{2}]=R_{1}\\\\\textbf{Dehydrogenation of tertiary alcohols with Cu yields alkenes.} \end{minipage}}$
