How could we compare rates of Wurtz reaction?


There are two mechanisms for Wurtz reaction. Now if we have to compare the relative rates of reaction then how could we do it?

In one mechanism there is a generation of a free radical while for the other there is the generation of a carbanion. The order of effects that determine the stabilities of free radicals and carbanions are opposite and so I feel that comparing rates wouldn't be possible if we aren't given on which mechanism we have to compare.

NOTE - The halide atom is assumed to be same for two compounds for which we have to compare rates.


See the mechanism of wurtz reaction is done via free radical formation.
For anion that is for side product mechanism.
