Answer:
A thioether is formed as product with opposite configuration.
Explanation:
- (R)-2-octanol substitutes Cl from p-toluenesulfonyl chloride to produce p-toluenesulfonate derivative. Here stereochemistry of 2-octanol is retained as no bond breaking or bond formation takes place at chiral center.
- [tex]C_{6}H_{5}S^{-}[/tex] gives [tex]S_{N}2[/tex] reaction with p-toluenesulfonate derivative to produce a thioether with (S) configuration. Here inversion of configuration takes place due to backside attack by [tex]C_{6}H_{5}S^{-}[/tex].
- Structure of product has been shown below.

The reaction of p−toluenesulfonate and sodium benzenethiolate occurs by SN2 mechanism hence there is inversion of configuration and the chiral center.
In these series of reactions, p−toluenesulfonate is derived from (R)−2−octanol and p−toluenesulfonyl chloride. The product is shown in the images attached.
