Interpretation Introduction

Interpretation:

The other mixture of alkyl halide and sulfide that yield from the same sulfonium salt that ismentioned exampleand the selection of the combination of mixture that forms faster than the other one is to be determined.

Concept Introduction:

Sulfur is stronger nucleophile than oxygen hence it reacts with alkyl halides faster than that of ethers. The reaction of alkyl halide and sulfur follows ${\text{S}}_{\text{N}}\text{2}$ (nucleophilic substitution) reaction and results in the formation of sulfonium salt.
