Question

why is thf solution used in preparing grignard reagent

Answer 1

Grignard carbon is nucleophilic in nature. Using water or alcohol which is acidic in nature would protonate thegrignard carbon and hence destroygrignard reagent. ... as dry ehter is non acidic it is a good solvent for prepration of Grignard Reagent.

Answer 2

• An ether solvent, usually diethyl ether, is required for preparation of Grignard reagents....The higher boiling point of the cyclic ether provides more vigorous reaction conditions, but the rate of the reaction is also increased because THF solvates the Grignard reagent better than diethyl ether.
