Current Question (ID: 10856)

Question:

$\text{In an } S_N1 \text{ reaction on chiral center, there is:}$

Options:

1. 100% racemization
2. $\text{Inversion is more than retention leading to partial racemization.}$ (Correct)
3. 100% retention
4. 100% inversion

Solution:

$\text{Hint: Carbocation as an intermediate is formed.}$ $\text{In } S_N1 \text{ reaction, due to contact or intimate ion pair mechanism, there is slight more inversion product than retention product. This is a situation when nucleofuge (leaving group) has not separated completely or is still in contact with the carbocation intermediate not allowing the incoming nucleophile to attack from that side leading to more inversion.}$
