5-substituted-2-(chloromethyl)-1H-benzimidazole, structures of the synthesized compounds were proved by spectral methods of analysis ( FT-IR, 1H and 13C NMR ). All the target compounds were screened for their antibacterial activity toward gram-negative (E.coli, P. aeruginosa) and Gram-positive (B. subtilis, S. aureus) bacteria, most of the synthesized derivatives exhibited good to moderate activity toward both Gram-positive
