विकल्प

• \[\begin{array}{cc}
  \phantom{..............}\ce{O}\\
  \phantom{..............}||\\
  \ce{CH3 - CH2 - CH2 - C - CH3}
  \end{array}\]

• \[\begin{array}{cc}
  \phantom{.......}\ce{O}\\
  \phantom{.......}||\\
  \ce{CH3 - CH - C - CH3}\\
  |\phantom{.......}\\
  \ce{CH3}\phantom{....}
  \end{array}\]

• \[\begin{array}{cc}
  \ce{O}\\
  ||\\
  \ce{CH3 - CH2 - C - CH2 - CH3}
  \end{array}\]

• \[\begin{array}{cc}
  \phantom{.......................}\ce{O}\\
  \phantom{.......................}||\\
  \ce{CH3 - CH2 - CH2 - CH2 - C - H}
  \end{array}\]

Answer 1

\[\begin{array}{cc}
\phantom{.......}\ce{O}\\
\phantom{.......}||\\
\ce{CH3 - CH - C - CH3}\\
|\phantom{.......}\\
\ce{CH3}\phantom{....}
\end{array}\]

Explanation:

\[\begin{array}{cc}
\phantom{..}\ce{CH3COCH - CH3}\\
|\\
\phantom{...}\ce{\underset{Isopropyl methyl ketone}{CH3}}
\end{array}\]
