← ScienceWhich outcome reduces the stability of a chiral drug?
A)Racemization by keto-enol tautomerization✓
B)Enhanced London dispersion forces
C)Increased steric hindrance within crystal
D)Reduced intermolecular hydrogen bonding
💡 Explanation
Racemization lowers stability because it converts a single enantiomer to a mixture via keto-enol tautomerization in suitable molecular environments. Therefore, the drug becomes a mix of isomers, rather than retaining a single, active form by stronger bonding influences.
