Question

When the concentration of alkyl halide is tripled and the concentration of ion is reduced to half, the rate of SN2reaction increases by:

• A. 3 times
• B. 2 times
• C. 1.5 times
• D. 6 times

Answer 1

Answer: (C)

1.5 times

Answer 2

Rate of $S_{N}2 \propto \lbrack R - X\rbrack\left\lbrack Nu^{-} \right\rbrack$

}{r_{2} = 1.5r_{1}}$$
