B) Williamson continuous etherification process
C) Etard reaction
D) Gatterman-Koch reaction
Correct Answer: A
Solution :
| [a] The reaction of alkyl halides with sodium alkoxide or sodium phenoxide to form ethers is called Williamson synthesis. Here, in this reaction alkyl halide should be primary and alcoxide, e.g. should be bulkier as shown below, |
| \[\underset{\begin{smallmatrix} \,\,\text{Alkyl} \\ \,\,\text{halide} \end{smallmatrix}}{\mathop{R}}\,-\,X+\underset{\text{Sodium}\,\,\text{alcoxide}}{\mathop{R'\,-ONa}}\,\xrightarrow{\,}\,\underset{\text{Ether}}{\mathop{R-O-R'\,+NaX}}\,\] |
| \[C{{H}_{3}}-\underset{\begin{smallmatrix} | \\ C{{H}_{3}} \end{smallmatrix}}{\overset{\begin{smallmatrix} C{{H}_{3}} \\ | \end{smallmatrix}}{\mathop{C}}}\,-ONa\,+C{{H}_{3}}C{{H}_{2}}Cl\xrightarrow[-NaCl]{}\]\[C{{H}_{3}}-\underset{\begin{smallmatrix} | \\ C{{H}_{3}} \end{smallmatrix}}{\overset{\begin{smallmatrix} C{{H}_{3}} \\ | \end{smallmatrix}}{\mathop{C}}}\,-O-C{{H}_{2}}-C{{H}_{3}}\] |
