The correct answer is: \( \mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{COCH}_{3} \)

Acyl chlorides upon treatment with Grignard reagent and a metal halide, yield ketones.For example, when cadmium chloride is reacted with the Grignard reagent, dialkylcadmium is formed. Dialkylcadmium thus formed is further reacted with acyl chlorides to form ketones.
