Question

Which among the following statements is not correct about S_N2 reaction mechanism?

Options

• Rate of reaction is dependent on the concentration of nucleophiles.

• Nucleophile attacks the carbon atom from the side opposite to halogen.

• Bond formation and bond breaking occur simultaneously.

• S_N2 mechanism is observed in tertiary alkyl halides.

Answer 1

S_N2 mechanism is observed in tertiary alkyl halides.

Explanation:

Tertiary alkyl halides do not react according to the S_N2 mechanism because the carbon that the nucleophile is intended to target is occupied in this instance. The nucleophile's approach is thus prevented.
