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

    Answer:

                    Grignard reagents do form ketones with acid chlorides but the reaction does not stop at this stage. Ketones further take part in the reactions with Grignard reagents to give tertiary alcohols. Therefore, dialkyl cadmium is used which reacts with only the acid chlorides and not with ketones. For details, consult section 13.6.
