Question

Write the major product in the following reactions: (1) Chlorobenzene + Na/dry ether

Hint:

Aryl halide + Na (dry ether) → Fittig reaction → biaryl formation (e.g., biphenyl).

Answer 1

This is Fittig reaction (coupling of aryl halides). \[ 2C_6H_5Cl + 2Na \rightarrow C_6H_5{-}C_6H_5 + 2NaCl \] Product:
Biphenyl
