Solution :
TIPS/Formulae :
Compounds having \[\underset{\begin{smallmatrix}
\parallel \\
O
\end{smallmatrix}}{\mathop{-C-}}\,C{{H}_{3}}\] groups show positive
iodoform test.
Hence, \[C{{H}_{3}}-C{{H}_{2}}-C{{H}_{2}}\underset{\begin{smallmatrix}
\parallel \\
O
\end{smallmatrix}}{\mathop{-C-}}\,C{{H}_{3}}\]
( pentanone - 2 ) gives this test.
