Vedclass · Answer

(B) Compounds containing the $CH_3CO-$ group or those that can be oxidized to this group (like $CH_3CH(OH)-$ group) give a positive iodoform test.Ethyl alcohol $(CH_3CH_2OH)$ is oxidized to acetaldehyde $(CH_3CHO)$ by $I_2/NaOH$,which then reacts to form iodoform $(CHI_3)$.The reaction is:$CH_3CH_2OH$ $\xrightarrow{I_2/NaOH} CH_3CHO$ $\xrightarrow{I_2/NaOH} CI_3CHO$ $\xrightarrow{NaOH} CHI_3 + HCOONa$
