Dialkyl cadmium is used to prepare ketones from acid chlorides and not from Grignard reagents. Assign reason.

Explanation

Dialkyl cadmium is less reactive than Grignard reagent because cadmium is less electropositive (electronegativity = 1.7) than magnesium (electronegativity = 1.2). Therefore, dialkyl cadmium reacts with more reactive acid chlorides to give ketones but donot react further with less reactive ketones so formed, to give tert-alcohols. But, Grignard reagents being more reactive not only react with acid chlorides but also with ketones formed to give tert-alcohols,
