Answer 2

The correct answer is option (c) Dimethyl cadmium.

Explanation:

• Dimethyl cadmium reagents can be used to prepare ketone from acid chloride
• Grigard reagents do form ketones with acid chlorides but the reactions do not stop at this stage.
• Ketones then, takes part in the reactions with Grignard reagents to form tertiary alcohols.
• So, dialkyl cadmium is used which reacts with only the acid chlorides and not with ketones.
• Hence, the correct answer is option c i.e Dimethyl cadmium.
