An organic compound X on treatment with acidified K2Cr2O7 gives a compound Y which reacts with I2 and Na2CO3 to form triiodomethane. The compound X is:

The correct option is D CH3CH(OH)CH3The compound Y should be a ketone as it is responding to iodoform test. Since it is formed by treating X with potassium dichromate(acidic) X should be a secondary alcohol. X is CH3CH(OH)CH3.

An organic compound $X$ on treatment with acidified $K_{2} C r_{2} O_{7}$ gives a compound $Y$ which reacts with $I_{2}$ and $N a_{2} C O_{3}$ to form triiodomethane. The compound $X$ is:

The correct option is D $C H_{3} C H (O H) C H_{3}$
The compound $Y$ should be a ketone as it is responding to iodoform test. Since it is formed by treating $X$ with potassium dichromate(acidic) $X$ should be a secondary alcohol. $X$ is $C H_{3} C H (O H) C H_{3}$ .
