Vedclass · Answer

(C) The reaction with $NaOH + I_2$ is the iodoform test,which is given by compounds containing the $CH_3CO-$ group or $CH_3CH(OH)-$ group. $1$. Acetone $(CH_3COCH_3)$ contains the $CH_3CO-$ group and gives a positive iodoform test. $2$. Acetaldehyde $(CH_3CHO)$ contains the $CH_3CO-$ group and gives a positive iodoform test. $3$. Acetophenone $(C_6H_5COCH_3)$ contains the $CH_3CO-$ group attached to a phenyl ring and gives a positive iodoform test. $4$. Benzaldehyde $(C_6H_5CHO)$ does not contain the $CH_3CO-$ or $CH_3CH(OH)-$ group,so it does not give a yellow precipitate of iodoform $(CHI_3)$.

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