Question

Heating together sodium ethoxide and ethyl chloride will give:

• A. Ethyl alcohol
• B. Ether
• C. Acetic acid
• D. Acetaldehyde

Answer 1

The correct option is B Ether

An important laboratory method used for the preparation of symmetrical and unsymmetrical ethers is Williamson synthesis. In this method, an alkyl halide is allowed to react with sodium alkoxide to form ethers.
So, heating of sodium ethoxide and ethyl chloride together will give diethyl ether.
$\underset{\text{Ethyl chloride}}{C{H}_{3}C{H}_{2}Cl}+\underset{\text{Sodium ethoxide}}{C{H}_{3}C{H}_2{O}^{-}N{a}^{+}}\to \underset{\text{Diethyl ether}}{C{H}_{3}C{H}_2-O-C{H}_{2}C{H}_3}+NaCl$
So, the correct option is $\text{(a)}$
