प्रश्न
Why is it necessary to avoid even traces of moisture during the use of Grignard reagent?
उत्तर
Grignard reagents are highly reactive substances. They react with any source of proton to form hydrocarbons. Even water is sufficiently acidic to convert it into the corresponding hydrocarbon. So it is necessary to avoid even traces of moisture with the Grignard reagent as they are highly reactive.
