Question

Which of the following statements regarding the $S_{N}1$reaction shown by alkyl halide is not correct?

• A. The added nucleophile plays no kinetic role in $S_{N}1$reaction
• B. The $S_{N}1$reaction involves the inversion of configuration of the optically active substrate.
• C. the $S_{N}1$reaction on the chiral starting material ends up with racemization of the product.
• D. the more stable the carbocation intermediate the faster the $S_{N}1$reaction.

Answer 1

Answer: (B)

The $S_{N}1$reaction involves the inversion of configuration of the optically active substrate.

Answer 2

In $S_{N}1$reaction, rate of substitution depends on the concentration of substrate. In case of $S_{N}1$reaction there is racemization. $S_{N}1$reaction will be faster, if carbocation fomed is more stable.
