||\phantom{.........}\\
\ce{O}\phantom{.........}
\end{array}\]

Answer 1

Overall reaction:

\[\begin{array}{cc}
\ce{CH3 - CH2 - CH2 - C - CH3 ->[H^+][HO - CH2 - CH2 - OH] CH3 - CH2 - CH2 - C - CH3}\phantom{.}\\
\phantom{..................}||\phantom{..........................................}/\phantom{.....}\backslash\phantom{..}\\
\phantom{.............}\ce{\underset{(2-Pentanone)}{O}}\phantom{....................................}\ce{O}\phantom{......}\ce{O}\phantom{}\\
\phantom{............................................................}|\phantom{.......}|\phantom{..}\\
\phantom{.............................................................}\ce{\underset{(2-Pentanone ethylene ketol)}{CH2 - CH2}}
\end{array}\]
