Alcohol basicity is key to understanding their behavior in chemical reactions, such as accepting protons and undergoing dehydration to form alkenes. Factors like molecular structure, electron-donating or withdrawing groups, solvent effects, and steric hindrance influence an alcohol's basicity. The basicity impacts reaction rates, product stability, and is assessed by pKa values through titration.
