In Wurtz reaction of alkyl halides with sodium the reactivity order of these halides is:
RI>RBr>RCl
RCl>RBr>RI
RBr>RI>RCl
None of the these
Larger is C-X bond length; more is reactivity
The order of reactivity of the following alkyl halides for an SN2 reaction is
The order of reactivity of haloalkenes is RI>RCl>RBr
