Question

If pyridine is added to the reaction mixture of an alcohol and thionyl chloride ($SOCl_2$), how does it change the mechanism and stereochemistry?

Prashant Kotian · Accepted Answer

Correct answer: C. Pyridine acts as a base to neutralize the byproduct, freeing the ion. The free acts as an external nucleophile, attacking from the backside via an pathway to cause stereochemical inversion.
