Question

Which of the following statements concerning SN2 reactions of alkyl halides is not correct?
Options
A The rate of reaction depends on the concentration of the nucleophile.
B The rate of reaction depends on the concentration of the alkyl halide.
C The rate of reaction of a particular alkyl bromide depends on the steric accessibility of the carbon of the C-Br bond.
D All alkyl iodides react more rapidly than all alkyl chlorides.
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

While iodides are better leaving groups than chlorides, it is not true that all alkyl iodides react more rapidly than all alkyl chlorides. The structure of the alkyl group (primary, secondary, tertiary) also greatly affects the rate. A tertiary alkyl chloride may react faster than a primary alkyl iodide due to steric factors.

Hint

Is the leaving group the only factor affecting SN2 rate?
