    B)  \[{{C}_{2}}{{H}_{5}}OH+CaOC{{l}_{2}}\xrightarrow[{}]{{}}\]a anaesthetic

    C)  \[C{{H}_{3}}COH+{{I}_{2}}+NaOH\xrightarrow[{}]{{}}\]a yellow colour precipitate

    Solution :

     \[\underset{acetone}{\mathop{C{{H}_{3}}-\underset{\begin{smallmatrix}  || \\  O \end{smallmatrix}}{\mathop{C}}\,-C{{H}_{3}}}}\,+CHC{{l}_{3}}\xrightarrow[{}]{{}}\underset{chloretone}{\mathop{C{{H}_{3}}-\underset{\begin{smallmatrix}  | \\  CC{{l}_{3}} \end{smallmatrix}}{\overset{\begin{smallmatrix}  C{{H}_{3}} \\  | \end{smallmatrix}}{\mathop{C}}}\,-OH}}\,\] Chloretone is used as a hypnotic drug, not a solvent.
