Interpretation Introduction

(a)

Interpretation:

The complete mechanism and the major organic product for given reaction is to be drawn.

Concept introduction:

Sulfonyl chloride has the general form R-SO2Cl. When sulfonyl chloride is treated with an alcohol, a sulfonate ester is produced via a sulfonation reaction. In the mechanism of sulfonation reaction, the alcohol attacks the sulfonyl chloride in a nucleophilic addition-elimination sequence. The nucleophilic OH group attacks the S=O group of the sulfonyl chlorides. In the second step, pyridine is added to the reaction for deprotonation. Nucleophilic elimination takes place in the third step. An alcohol changes a poor HO- leaving group into a great RSO3- leaving group in sulfonation step. Sulfonation of an alcohol occurs with retention of configuration at the C-OH carbon.
