The reaction is an SN2 reaction with iodide acting as the nucleophile attacking the carbon center of the bromoalkane. The iodide ion has a higher nucleophilicity compared to the chloride and fluoride ions due to its larger size, and it is able to displace the bromine ion. The major product is the product with the highest yield, which is II, where the iodide ion has completely replaced the bromine atom. The other products, I, III, and IV, may also be formed to some extent, but they would be present in lesser amounts.
