Vedclass · Answer

(C) The preparation of ethers via the Williamson ether synthesis involves the reaction of an alkoxide or phenoxide ion with a primary alkyl halide. For the synthesis of Methyl phenyl ether $(Ph-O-Me)$,the phenoxide ion $(PhO^{-} Na^{+})$ acts as a nucleophile and attacks the methyl halide $(MeBr)$ via an $S_N2$ mechanism. The reaction is: $PhO^{-} Na^{+} + Me-Br \xrightarrow{S_N2} Ph-O-Me + NaBr$. Thus,the correct condition is $PhO^{-} Na^{+}$ and $MeBr$.

The suitable reaction condition for the preparation of Methyl phenyl ether is:
