Which of the following statements is not correct about Sn2 reactions of alkyl halides?

Question

Which of the following statements is not correct about Sn2 reactions of alkyl halides? (A) Nucleophile attacks the carbon from the side opposite to where the leaving group is attached (B) The bond formation and bond breaking take place in one step (C) The rate of reaction depends upon the concentration of nucleophile (D) SN2 mechanism is predominant in tertiary alkyl halides

Tardigrade Admin · Accepted Answer

The option D is incorrect as in case of tertiary alkyl halides, the carbon on which nucleophile is supposed to attack is is crowded, making this reaction less feasible.

Q. Which of the following statements is not correct about $S_{n} 2$ reactions of alkyl halides?

Nucleophile attacks the carbon from the side opposite to where the leaving group is attached

The bond formation and bond breaking take place in one step

The rate of reaction depends upon the concentration of nucleophile

$S_{N} 2$ mechanism is predominant in tertiary alkyl halides

The option D is incorrect as in case of tertiary alkyl halides, the carbon on which nucleophile is supposed to attack is is crowded, making this reaction less feasible.
