Question

In SN1 and SN2 reactions:
(A). SN1 is a unimolecular reaction with first-order kinetics, while SN2 is a bimolecular reaction with second-order kinetics.
(B). In SN2, the reaction proceeds through the formation of a carbocation, while SN1 does not.
(C). SN2 is a stereospecific reaction. The product forms with inversion of configuration only.
(D). SN1 reaction is favored in the presence of a weak base or poor nucleophile.
Choose the correct answer from the options given below:

• A. (A), (B), and (D) only.
• B. (A), (B), and (C) only.
• C. (A), (C), and (D) only.
• D. (B), (C), and (D) only.

Hint:

In SN1, the leaving group departs first, leading to a carbocation intermediate, while in SN2, the nucleophile attacks the electrophile simultaneously.

Answer 1

The Correct Option is C

• \( \text{SN1} \) reactions are unimolecular with first-order kinetics, while \( \text{SN2} \) reactions are bimolecular.
• \( \text{SN2} \) reactions occur with inversion of configuration, while \( \text{SN1} \) reactions do not involve the formation of a carbocation.
• \( \text{SN1} \) reactions are favored by poor nucleophiles.
