$CH_3-CH_2-OH$

Vedclass · Answer

(A) The iodoform test is given by compounds containing the $CH_3-CO-$ group or the $CH_3-CH(OH)-$ group.$A$. Ethanol $(CH_3-CH_2-OH)$ contains the $CH_3-CH(OH)-$ group. During the reaction with $I_2$ and $NaOH$,it is first oxidized to acetaldehyde $(CH_3-CHO)$,which then undergoes the iodoform reaction to form yellow crystals of iodoform $(CHI_3)$.$B$. Propanal $(CH_3-CH_2-CHO)$ does not contain the required structural group.$C$. Ethane$-1,2-$diol $(HO-CH_2-CH_2-OH)$ does not contain the required structural group.Therefore,the correct option is $A$.
