In an alkyl halide, the halogen serves 2 functions that render the alkyl halide reactive towards substitution and elimination processes. One is that halgens serve as leaving groups and substitution/elimination reactions can only occur when a leaving group is present. What is the other reason? The halogens have pką values above zero, making them weaker acids and more likely to participate in dissolution. The halogen repels electron density rendering the adjacent carbon atom nucleophilic and therefore subject to attack by an electrophile. The halogen is usually in an allylic postion and therefore does not participate in resonance, making it less stable and more likely to react. The halogen withdraws electron density rendering the adjacent carbon atom electrophilic and therefore subject to attack by a nucleophile.

What was the driving goal of the late nineteenth-century Can Vuong resistance movement in what is now Vietnam? to establish a communist republic in the region to establish a democratic republic of ethnic Vietnamese only to ally with the British as a means of expelling the French from the region to bring the local king back to power and expel the French to accept French control but extract far better terms for the local population under French rule
