Vedclass · Answer

(C) The correct answer is $C$. Ethyl alcohol $(C_2H_5OH)$ contains a $CH_3CH(OH)-$ group,which gives a positive iodoform test with $NaOH$ and $I_2$,forming a yellow precipitate of iodoform $(CHI_3)$. $C_2H_5OH + 4I_2 + 6NaOH \rightarrow CHI_3 + HCOONa + 5NaI + 5H_2O$. Methyl alcohol $(CH_3OH)$ does not contain this group and does not form a yellow precipitate with $NaOH$ and $I_2$.
