Vedclass · Answer

(C) The iodoform test is positive for compounds containing a methyl ketone group $(CH_3-CO-)$ or a methyl carbinol group $(CH_3-CH(OH)-)$. It is also positive for compounds that can be oxidized or halogenated to these forms,such as $\alpha$-halo ketones $(XCH_2-CO-)$. $(A)$ $CH_3-CO-CH_2OH$ is a methyl ketone. (Positive) $(B)$ $CH_2I-CH(OH)-CH_2OH$ can be oxidized to $CH_2I-CO-CH_2OH$,which contains the $CH_2I-CO-$ group. (Positive) $(C)$ $CHO-CO-Ph$ (Phenylglyoxal) does not contain a methyl group or a halomethyl group attached to the carbonyl carbon. (Negative) $(D)$ $CH_3-CH(OH)-Ph$ is a methyl carbinol. (Positive) Therefore,$(C)$ does not give the iodoform test.

Which of the following compounds does not give the iodoform test?
