Question

Explain why Grignard reagents should be prepared under anhydrous conditions?

Chemical Equations/Structures
Explain

Solution

Grignard reagents are very reactive. In the presence of moisture, they react to give alkanes.

\[\ce{\underset{reagent}{\underset{Grigrard}{\overset{\delta-}{R} \overset{\delta +}{M}g \overset{\delta -}{X}}} + H2O -> \underset{Alkane}{R - H} + Mg (OH) X}\]

Therefore, Grignard reagents should be prepared under anhydrous conditions.
