A

CH3OHC{{H}_{3}}OH

B

C2H5OH{{C}_{2}}{{H}_{5}}OH

C

CH3COCH3C{{H}_{3}}COC{{H}_{3}}

D

CH3CH OHCH3C{{H}_{3}}\underset{\begin{smallmatrix} | \\\ OH \end{smallmatrix}}{\mathop{CH}}\,C{{H}_{3}}

Answer

CH3OHC{{H}_{3}}OH

Explanation

Solution

Only those compound give lodoform test which has CH3COHHCH_3\overset{\underset{|}{O}H}{C}H- or CH3CO CH_3\overset{\underset{||}{O}}{C}- group. Hence, Methonal does not give lodoform test.
