Consider the reaction of 2-chloro-2-methylpentane with sodium iodide. Assuming no other changes, how would it affect the rate if one simultaneously doubled the concentration of 2-chloro-2-methylpentane and sodium iodide? Group of answer choices

The given question is incomplete, the complete question is:

Consider the reaction of 2-chloro-2-methylpentane with sodium iodide. Assuming no other changes, how would it affect the rate if one simultaneously doubled the concentration of 2 - chloro-2-methylpentane and sodium iodide? + NaCI + Nal CI A) no effect B) it would double the rate C) it would triple the rate D) it would quadruple the rate E) it would increase the rate 5 times

Answer:

The correct answer is option B, that is, it would double the rate.

Explanation:

Based on the given reaction, the reactant, that is, 2-chloro-2-methylpentane is a sterically crowded molecule, therefore, the formation of the product will take place by SN₁ reaction mechanism. The formation of carbocation takes place in the initial step and is considered as the rate-determining step.

The rate equation is R = K₁ [A]ⁿ

Here A is 2-chloro-2-methylpentane, therefore, if the concentration of A increases, the rate of the reaction will get double. Now the rate becomes, R = K₁ [A]²

In the given case, NaI or sodium iodide is a nucleophile, and the concentration of nucleophile is not present in the rate equation, it is a unimolecular reaction. So, option 1 cannot be correct.
