A) \[{{S}_{N}}1\] mechanism
B) nucleophilic addition
C) \[{{S}_{N}}2\]mechanism
D) \[{{S}_{E}}\]mechanism
Correct Answer: C
Solution :
Williamson's synthesis: A reaction in which sodium or potasium alkoxide is heated with an alkyl halide to give ether by the reaction sample as well as mixed ethers can be prepared. This is an example of nucleophilic substitution and follows\[{{S}_{N}}2\]mechanism. \[RONa+XR\xrightarrow{\Delta }\underset{simple}{\mathop{ROR}}\,+\underset{ether}{\mathop{NaX}}\,\] \[RONa+XR'\xrightarrow{\Delta }\underset{mixed\,ether}{\mathop{R-O-R'}}\,+NaX\]
