Question

In Williamson's synthesis, ethoxyethane is prepared by

• A. passing ethanol over heated alumina
• B. heating sodium ethoxide with ethyl bromide
• C. treating ethyl alcohol with excess of H'. $H_2SO_4$ at 430 -- 440 K
• D. heating ethanol with dry $Ag_2O$

Answer 1

Answer: (B)

heating sodium ethoxide with ethyl bromide

Answer 2

$^{ CH_3CH_2ONa }_{ sodium ethoxide } \, + \, ^{C_2 H_5 Br}_{ bromo \, ethane} \, \xrightarrow[synthesis] {Williamson's } \, ^{ CH_3 CH_2 OCH_2 CH_3}_{ ethoxyethane } + NaBr$
