question_answer

\[ArX+2Na+ArX\xrightarrow{Dry\,\,ether}Ar-Ar+NaX\]Name of the reaction is

A)  Williamsons synthesis

B)  Fittig reaction

C)  Wurtz reaction

D)  Sandmeyers reaction

E)  Wurtz-Fittig reaction

Correct Answer: B

Solution :

                In, Fittig reaction, only halide reacts with sodium in the presence of ether e.g. And in Wurtz-Fitting reaction, aryl halide and alkyl halide can react with sodium in the presence of ether to form substituted benzene. And in Wurtz reaction, only alkyl halides on reaction with sodium in the presence of ether form alkane. e.g. \[C{{H}_{3}}Cl+2Na+ClC{{H}_{3}}\xrightarrow{{}}C{{H}_{3}}-C{{H}_{3}}+2NaCl\]
