2.(S)-2-butanol slowly racemizes in dilute acid solution.Propose a mechanism.

3.Use the electronic factors to explain why hydrogen attached to a nitrogen of a sulfonamide is acidic.

Answer 1

1.

2.

3.Sulfonamide acidity and the charge of the SO2 group were not linearly correlated electronic factors. These findings drove us to the present study and sulfonamido hydrogen atoms than in nitrogen
