Ethane thiol (R–SH) is more acidic than ethanol (R–OH) because the S–H bond is weaker and sulfur is less electronegative than oxygen, allowing easier release of the proton (H⁺). The conjugate base of a thiol (RS⁻) is also more stable due to sulfur’s larger atomic size.
Which one is more acidic? Ethane thiol, Ethanol, Both A and B, None of these
