Question

What is the product of the SN2 reaction of this amine with one equivalent of methyl iodide, assuming a neutralizing workup?

A) Amine iodide
B) Methylamine
C) N-Methylamine
D) N-Methylammonium iodide

Answer 1

The product of the SN2 reaction between an amine and methyl iodide, with neutralizing workup, is N-Methylammonium iodide. option d is correct

Step-by-step explanation:

option d is correct The product of the SN2 reaction of an amine with one equivalent of methyl iodide, followed by neutralizing workup, is N-Methylammonium iodide. In such a reaction, the amine will act as a nucleophile and attack the methyl iodide, leading to the substitution of the iodide ion with the nitrogen off the amine. Consequently, the nitrogen gains a positive charge, forming an ammonium ion, which will be associated with the iodide ion as its counterion due to the neutralization step in the workup. This results in the formation of N-Methylammonium iodide, which is the correct answer (D).

The product of the SN2 reaction of this amine with one equivalent of methyl iodide, assuming a neutralizing workup, is N-Methylammonium iodide (D).
