Question

Ethyl chloride is converted into diethyl ether by

• A. Wurtz synthesis
• B. Grignard reaction
• C. Perkin- reaction
• D. Williamson- synthesis

Answer 1

Answer: (D)

Williamson- synthesis

Answer 2

$C_2H_5 C1+NaOC_2 H_5 \longrightarrow$
\hspace30mm C_2H_5 -0-C_2 H_5+NaC1
It is an example of Williamson- synthesis.
Limitations of Williamson- Synthesis
$3^\circ$ alkyl halide does not gives Williamson's synthesis
if $3^\circ$ alkyl halide used in reaction then alkene
formed.
