An industrial route for making ethyl ethanoate has been developed by using inexpensive sources of ethanol. $\text{CH}_3\text{CH}_2\text{OH} \xrightarrow[\text{Cu catalyst}]{-2[\text{H}]} \text{CH}_3\text{CHO} \xrightarrow[\text{Cu catalyst}]{+\text{CH}_3\text{CH}_2\text{OH}} \text{CH}_3\text{CH(OH)OCH}_2\text{CH}_3 \xrightarrow[\text{Cu catalyst}]{-2[\text{H}]} \text{CH}_3\text{CO}_2\text{CH}_2\text{CH}_3$ Which process takes place at some point in this reaction sequence?
- Aelectrophilic addition
- Bnucleophilic addition
- Cnucleophilic substitution
- Dreduction
