WebAnswer: Thiophenol has a greater acidity than Phenol. The reason to this thiophenol has a pKa of 6 as to that phenol has 10 (The lower the pKa, the stronger is the acid!). This is … Thiophenol has appreciably greater acidity than does phenol, as is shown by their pKa values (6.62 for thiophenol and 9.95 for phenol). A similar pattern is seen for H2S versus H2O, and all thiols versus the corresponding alcohols. Treatment of PhSH with strong base such as sodium hydroxide (NaOH) or sodium metal affords the salt sodium thiophenolate (PhSNa). The thiophenolate is highly nucleophilic, which translates to a high rate of alkylation. Thus, treat…
