Question
If pyridine is added to the reaction of 2-butanol with $SOCl_2$, what is the new mechanism and stereochemical outcome?
Answer: A
💡 Solution & Explanation
Pyridine neutralizes the $HCl$ byproduct, freeing the $Cl^-$ ion to act as an external nucleophile. It performs a backside attack, switching the mechanism to $S_N2$ (Inversion).
