JEE Main levelSingle correct optionDifficulty 2 of 3ro065

Acetophenone, $C X_{6} H X_{5} - CO - CH X_{3}$ , is warmed with $I X_{2}$ and aqueous $NaOH$ . The products are

A $C X_{6} H X_{5} CHO$ and $CHI X_{3}$
B $C X_{6} H X_{5} COONa$ and $CH X_{3} I$
C $C X_{6} H X_{5} COONa$ and $CHI X_{3}$
D $C X_{6} H X_{5} CH X_{2} COONa$ and $CHI X_{3}$

Answer: C

The methyl ketone is tri-iodinated to

C X_{6} H X_{5} COCI X_{3}

. Hydroxide then attacks the carbonyl carbon and expels

CI X_{3} X^{-}

, which is protonated to iodoform. The acyl part leaves as sodium benzoate.
