## Abstract The 1,3‐tautomerism associated with 2‐(2‐hydroxy‐5‐substituted‐aryl)benzimidazoles was studied in different solvents. The effect of hydrogen bonding involving the hydroxyl group of the 2‐aryl ring on the tautomerism was investigated using NMR spectroscopy. The influence of the solvent c
