Give reactions of aryl halides with metals.

(N/A) $(i)$ Wurtz-Fittig reaction: $A$ mixture of an alkyl halide and an aryl halide gives an alkylarene when treated with sodium in dry ether.
$(ii)$ Fittig reaction: Aryl halides also give analogous compounds when treated with sodium in dry ether,in which two aryl groups are joined together.
$(iii)$ Grignard reaction: The reaction of an aryl halide with magnesium in the presence of dry ether gives an aryl magnesium halide,which is known as a Grignard reagent.
