Question

By which of the following procedures can ethyl methyl ether be obtained?

• A. $\ce{2C2H5I + Ag2O ->[\Delta]}$
• B. $\ce{C2H5OH + CH2N2 ->[HBF_4][\Delta]}$
• C. $\ce{C2H5ONa + C2H5I ->[\Delta]}$
• D. $\ce{2C2H5OH ->[Al_2O_3][250^{\circ}C]}$

Answer 1

Answer: (B)

$\ce{C2H5OH + CH2N2 ->[HBF_4][\Delta]}$

Answer 2

${C2H5OH + }$ $\underset{\text{Diazomethane}}{ {CH_2N_2}}$ ${->[HBF_4]}$ $\underset{\text{Ethyl methyl ether}}{ {CH3OC2H5}}$ {+ N2 ^}
