A) \[C{{H}_{3}}CN\]
B) \[C{{H}_{3}}OH\]
C) \[C{{H}_{3}}COC{{H}_{3}}\]
D) \[{{C}_{6}}{{H}_{5}}OH\]
Correct Answer: C
Solution :
Compounds containing\[\left( C{{H}_{3}}--\overset{O}{\mathop{\overset{||}{\mathop{C}}\,}}\,-- \right)\]group give the iodoform test. \[C{{H}_{3}}--\overset{O}{\mathop{\overset{||}{\mathop{C}}\,}}\,--C{{H}_{3}}+3{{I}_{2}}+NaOH\xrightarrow{{}}\]\[\underset{Iodoform\,(yellow\,ppt)}{\mathop{CH{{I}_{3}}+HCOONa+{{H}_{2}}O}}\,\] Hence only acetone gives the iodoform test.
