Question

Heavily evaluate the strict kinetic reactivity of standard pure simple alkyl halides directly natively towards concerted bimolecular nucleophilic substitution ($S_N2$). Which order is flawlessly mathematically correct?

Answer: B

💡 Solution & Explanation

$S_N2$ proceeds entirely via a strictly synchronized one-step backside attack. The paramount absolute barrier is pure physical steric hindrance immediately directly at the $\alpha$-carbon. Methyl halides lack bulky alkyl groups, allowing the uniquely fastest kinetic substitution rate.
