उत्तर

\[\ce{I2}\] and \[\ce{NaOH}\] solution

Explanation:

\[\begin{array}{cc}
\phantom{......................}\ce{O}\phantom{....................................}\ce{O}\phantom{..............}\\
\phantom{....................}||\phantom{.....................................}||\phantom{............}\\
\phantom{}\ce{CH3CH = CH - CH2 - C - CH3 ->[I2 + NaOH] CH3CH = CHCH2 - C - ONa + CHI3}\\
\phantom{............................................}\ce{↓ H2O}\\
\phantom{.......................................................}\ce{O}\\
\phantom{.......................................................}||\\
\phantom{.........................................}\ce{CH3CH = CHCH2 - C - OH}
\end{array}\]
