Question

Higher, extended ethers can be synthesized by reacting an alpha-halo ether with a Grignard reagent. In the reaction of $CH_3-O-CH_2-Cl$ with $CH_3CH_2MgBr$, the Grignard reagent acts as:

Prashant Kotian · Accepted Answer

Correct answer: D. The alpha-halo ether acts as a highly reactive electrophilic substrate. The Grignard reagent provides a nucleophilic carbanion () that attacks the halogen-bearing carbon, displacing the chloride leaving group via to form .
