How do you convert the following? Propanone to Propan-2-ol
Show Hint
Solution and Explanation
Reduction of a ketone yields a secondary alcohol.
Step 2: Meaning
Propanone (acetone) requires the addition of hydrogen across its carbonyl double bond.
Step 3: Analysis
Mild reducing agents like sodium borohydride ($NaBH_4$), lithium aluminum hydride ($LiAlH_4$), or catalytic hydrogenation ($H_2/Ni$) efficiently perform this conversion.
Final Answer: By catalytic hydrogenation or by using reducing agents like $NaBH_4$. $CH_3-CO-CH_3 \xrightarrow{NaBH_4} CH_3-CH(OH)-CH_3$
