Question

The Wurtz-Fitting reaction may be employed to unite aryl and redicals although it is impreactical for the union of unlike aliphatic radicals. Explain.

Answer 1

Dialkyls, differ and aryl-alkyls formed by Wurtz-Fitting reaction differ in their boiligg points. Diaryls have high boiling points, aryl-alkyls have moderate boiling points and the dialkyls have low boiling points. Diaryls have high boiliing points, aryl-alkyls have moderate boiling points and the dialkyls have low boiling point. Hence, it is easy to separate these products by fractional distillation. Union of two unlike alkyl radicals produce three different alkenes and their seperation into individual members is very difficult.
