Q. Which of the following set of statements regarding the $S_{N}1$ reaction shown by alkyl halide is correct here?
$1.$ the $S_{N}1$ reaction on the chiral starting material end up with racemization of the product
$2.$ The more stable the carbocation intermediate the faster the $S_{N}1$ reaction
$3.$ the added nucleophile plays no kinetic role in $S_{N}1$ reaction
$4.$ The $S_{N}1$ reaction involves the inversion of configuration of the optically active substrate

Solution:

In $S_{N}1$ reaction, rate of substitution depends on the concentration of substrate only and not upon nucleophile. In case of $S_{N}1$ reaction there is recemization. $S_{N}1$ reaction will be faster, if carbocation formed is more stable.
