$NaHSO_3$

Vedclass · Answer

(C) Acetaldehyde $(CH_3CHO)$ contains a $CH_3CO-$ group,which gives a positive iodoform test with $NaOH/I_2$ (forming a yellow precipitate of $CHI_3$).Acetophenone $(C_6H_5COCH_3)$ also contains a $CH_3CO-$ group and gives a positive iodoform test.However,acetaldehyde reacts with $NaHSO_3$ to form a crystalline bisulfite addition product,whereas acetophenone does not react with $NaHSO_3$ due to steric hindrance.Therefore,$NaHSO_3$ is used to distinguish between them.

Which of the following is used to distinguish between acetophenone and acetaldehyde?
