The reaction you're referring to is a nucleophilic substitution (SN2) reaction. In an SN2 reaction, the nucleophile (in this case, hydroxide) attacks the substrate (in this case, (S)-2-chloropentane) from the opposite side of the leaving group (chloride), leading to an inversion of stereochemistry and the formation of (R)-2-pentanol.

The rate of an SN2 reaction is influenced by the nucleophilicity of the nucleophile and the polarity of the solvent. Hydroxide is a strong nucleophile, so it will react quickly regardless of the solvent. However, the solvent can still have a significant effect on the reaction rate.

Polar protic solvents, like water and methanol, can hydrogen bond with the nucleophile, which can actually slow down the reaction by making the nucleophile less available for reaction. Polar aprotic solvents, like acetonitrile, cannot hydrogen bond with the nucleophile, so they do not slow down the reaction in this way. Therefore, acetonitrile would likely be the solvent in which this reaction would occur the fastest.

Ammonia is a polar protic solvent, but it is also a weak base and a weak nucleophile. Therefore, it would not be a good choice for this reaction, as it could compete with the hydroxide for reaction with the (S)-2-chloropentane.

So, the answer is Acetonitrile.
