Practice mode Alkyl Halides

An alkyl halide reacts with OH⁻ by the SN2 mechanism. If is doubled and is tripled, the rate becomes ____.

Correct answer B. 6 times the original

Explanation

For SN2, rate = k[RX][OH⁻]. Both reactants appear to the first power, so doubling [RX] and tripling [OH⁻] multiplies the rate by 2 × 3 = 6, making it 6 times the original.
