Vedclass · Answer

(D) The iodoform test is given by compounds containing the $CH_3CO-$ group or the $CH_3CH(OH)-$ group. $C_2H_5OH$ contains the $CH_3CH(OH)-$ group,$CH_3CHO$ contains the $CH_3CO-$ group,and $CH_3COCH_3$ contains the $CH_3CO-$ group. $HCHO$ (formaldehyde) does not contain either of these groups,so it does not give a yellow precipitate of iodoform $(CHI_3)$ with $I_2$ and $NaOH$. Therefore,the correct option is $(D)$.

Which of the following does not give a yellow precipitate with $I_2$ and $NaOH$?
