- Rank in terms of reactivity towards the nucleophile. 1=least 4=mostPlease answer the two items. The following compounds are major products of an elimination reaction with an alkyl halide. Determine the structure of the alkyl halide. Write the overall reaction mechanism. Tip: Remember your Markovnikov’s rule. Follow the progress of the reaction and look at the stability of the intermediate products and transition states to determine the minor and major products.Polar aprotic solvents enhance the rate of an SN2 reaction by stabilizing the cations and the anions. changing the polarizibility of the nucleophile. raising the energy of the nucleophile. O lowering the energy of the nucleophile. Save for Later
