Chemistry - Halogen Derivative Question with Solution | TestHub

Question Explanation: Nucleophilic substitution reaction of Grignard reagents.

Concept: ${\mathrm{SN}}_2$ reaction with Grignard reagents.

Solution:

The Grignard reagent ( ${\mathrm{CH}}_3{}^{-}$) acts as a nucleophile and attacks the carbon atom bearing the better leaving group $(\mathrm{Cl})$ via an ${\mathrm{SN}}_2$ mechanism. The ether group $\left(-{\mathrm{OCH}}_3\right)$ is a poor leaving group and remains intact.

Final Answer: Option (A)
