Suitable alkyl, aryl or vinyl halides react with magnesium under anhydrous ether conditions to form which class of reagent?

Explanation

Suitable organic chlorides, bromides or iodides react with magnesium under anhydrous ether conditions to form organomagnesium halides, RMgX, called Grignard reagents. The organic group may be alkyl, aryl or vinyl. Tollens’ and Fehling’s reagents are aldehyde-test reagents; Hinsberg reagent is benzenesulfonyl chloride.
