Question
Give reason:
Reactions involving Grignard reagent must be carried out under anhydrous condition.
Solution
Grignard reagents are highly reactive compounds. They react with water or compounds containing hydrogen attached to the electronegative element. Hence, reactions involving the Grignard reagent must be carried out under anhydrous condition.
