The product formed in the following multistep reaction is:
\( \text{CH}_3 - \text{CH}_2 - \overset{\overset{\text{O}}{\parallel}}{\text{C}} - \text{OCH}_3 \)
\( \text{CH}_3-\text{CH}_2-\text{CH}_2-\text{CH}_2-\text{OH} \)
\(\text{CH}_3 - \text{CH}_2 - \overset{\overset{\text{OH}}{\mid}}{\text{CH}} - \text{CH}_3\)
