The rate of SN2 reaction becomes doubled if the _.
Correct answer: B. Concentration of substrate doubled
- A. Concentration of nucleophile doubled
- B. Concentration of substrate doubled
- C. Concentration of substrate tripled
- D. Concentration of substrate remains same
Explanation
The rate of SN2 reaction becomes doubled if the concentration of substrate is doubled. In an SN2 reaction, the rate of the reaction depends on the concentration of both the nucleophile and the substrate.

About Nucleophilic Substitution
Nucleophilic substitution replaces a leaving group in an alkyl halide when an electron-rich nucleophile attacks the carbon atom. The topic compares SN1 and SN2 mechanisms, including reaction conditions, substrate structure, solvent effects, nucleophile strength, carbocation formation and stereochemical changes, and distinguishes substitution from elimination.
