A) \[C{{H}_{3}}COC{{H}_{2}}I\]
B) \[IC{{H}_{2}}COC{{H}_{2}}I\]
C) \[C{{H}_{3}}COCH{{I}_{2}}\]
D) \[C{{H}_{3}}COC{{I}_{3}}\]
Correct Answer: B
Solution :
Mechanism of iodoform reaction takes place by two steps (i) lodonation of \[-\overset{O}{\mathop{\overset{|\,\,|}{\mathop{C}}\,}}\,-C{{H}_{3}}\]group to form\[-\overset{O}{\mathop{\overset{|\,\,|}{\mathop{C}}\,}}\,-C{{I}_{3}}\] \[C{{H}_{3}}-\overset{O}{\mathop{\overset{|\,\,|}{\mathop{C}}\,}}\,-C{{H}_{3}}\xrightarrow{O{{I}^{-}}}C{{H}_{3}}-\overset{O}{\mathop{\overset{|\,\,|}{\mathop{C}}\,}}\,-C{{H}_{2}}I+O{{H}^{-}}\] \[C{{H}_{3}}-\overset{O}{\mathop{\overset{|\,\,|}{\mathop{C}}\,}}\,-C{{H}_{2}}I\xrightarrow{O{{I}^{-}}}C{{H}_{3}}-\overset{O}{\mathop{\overset{|\,\,|}{\mathop{C}}\,}}\,-CH{{I}_{2}}+O{{H}^{-}}\]\[C{{H}_{3}}-\overset{O}{\mathop{\overset{|\,\,|}{\mathop{C}}\,}}\,-CH{{I}_{2}}\xrightarrow{O{{I}^{-}}}C{{H}_{3}}-\overset{O}{\mathop{\overset{|\,\,|}{\mathop{C}}\,}}\,-C{{I}_{3}}+O{{H}^{-}}\] (ii) Elimination of \[-C{{I}_{3}}\]as: \[C{{I}_{3}}\]anionYou need to login to perform this action.
