Question

Higher, more complex ethers can be synthesized using organometallic chemistry. When an $\alpha$ -halo ether ($R-O-CH_2-Cl$) reacts with a Grignard reagent ($R'-MgX$), what describes the role of the Grignard reagent?

Prashant Kotian · Accepted Answer

Correct answer: B. -halo ethers are highly reactive electrophiles. The Grignard reagent () provides a strongly nucleophilic carbanion equivalent () that attacks the carbon bearing the halogen, displacing the chloride leaving group via and extending the carbon chain.
