A) Perkins reaction
B) Wurtz-Fittig reaction
C) Wurtz reaction
D) Williamsons synthesis
Correct Answer: D
Solution :
Williamsons synthesis This reaction is used to prepare both symmetrical and unsymmetrical ethers by treating alkyl halide with sodium alkoxide or sodium phenoxide. \[\underset{\begin{smallmatrix} ethyl \\ chloride \end{smallmatrix}}{\mathop{{{C}_{2}}{{H}_{5}}Cl}}\,+\underset{\begin{smallmatrix} sodium \\ ethoxide \end{smallmatrix}}{\mathop{{{C}_{2}}{{H}_{5}}ONa}}\,\xrightarrow{{}}\underset{diethyl\text{ }ether}{\mathop{{{C}_{2}}{{H}_{5}}O{{C}_{2}}{{H}_{5}}}}\,+NaCl\]Perkins reaction Benzaldehyde on heating with acetic anhydride in the presence of sodium acetate and the hydrolysis of product obtained gives \[\alpha ,\beta \] unsaturated acid, cinnamic acid.You need to login to perform this action.
