SUMMARY
NaSH (sodium hydrosulfide) is less basic than NaOH (sodium hydroxide) in organic synthesis, as evidenced by the acidic adducts they produce; NaSH yields H2S while NaOH produces H2O. This difference in acidity indicates that NaSH's basicity is lower, which is crucial for reactions involving sensitive functional groups, such as amides in pyridine derivatives. When refluxing a bromo pyridine with NaSH in ethanol, caution is advised to prevent hydrolysis of the amide moiety due to NaSH's basicity.
