S Propanone + Cadmium chloride

(A)Ethyl chloride
(B)Ethylene dichloride
(C)Ethanoyl chlorideCorrect
(D)Ethylidene dichloride

Answer: (C)

Solution

Dialkylcadmium reagents () react with acyl chlorides to give ketones (Rosenmund-type ketone synthesis): 2R'COCl + R_2Cd \rightarrow 2R'COR + CdCl_2. For propanone () with dimethylcadmium, supplies the group, so the acid chloride must be
