Diazomethane () is utilized to synthesize methyl ethers from alcohols. Which specific catalyst is st — Alcohols Phenols and Ethers Chemistry Question

💡 Solution & Explanation

According to the text, the action of diazomethane ($CH_2N_2$) on an alcohol to form a methyl ether requires a specific acidic catalyst, fluoroboric acid ($HBF_4$). The reaction proceeds as: $R-OH + CH_2N_2 \xrightarrow{HBF_4} R-O-CH_3 + N_2 \uparrow$.
